> therefore making it a more valuable language to acquire for business, diplomacy and travel
Learning a Chinese language for the business, diplomacy or travel opportunities is a stupid, stupid idea. In the English-speaking West, bwtween 1.6% and 5.0% of the population are native speakers of both some Chinese language and English. The business and diplomacy opportunities that require a Chinese-speaker all go to these people*.
Nobody's going to hire some rando to speak Mandarin when it's equally easy to hire a person who's as good as the natives, and got to spend the 3 years of effort one needs to learn Mandarin on picking up some other useful business skill.
Travel opportunities are not great, either: normally, you can visit the PRC for 15 days, you're railroaded throughout your whole trip, and you're required by law to stay in a select few hotels where the staff speak English anyway. If you're looking to learn a language for the tourism opportunities, you're much better served by learning Spanish, Russian, or for that matter Japanese, which allow you to visit a lot more otherwise hard-to-access destinations.
* You have a slight edge if you also speak some obscure language in a country with few English-speakers who nonetheless want to trade with China. There are very few such countries. All of Africa is out (English and French have very high penetration), as is South East Asia (Chinese itself has a high penetration), as is the Arab world: a few Eastern European countries such as Hungary might qualify, but guess what, Hungary also has a sufficient number of native Chinese speakers to saturate the demand in that niche market.*

Huh?
The tourist visa is I believe 90 days per entry (as it is for most countries), and valid for 10 years. There has been no foreign guest licensing requirement in the PRC since 2002, as far as I can tell, and even then it didn't seem to be a "select few" hotels, it was something any hotel could get, but probably a lot didn't because international tourism to China wasn't as big then. Some hotels will refuse foreign guests, apparently, but that's the hotel's individual decision and it doesn't seem to be widespread.
I know several non-Chinese people who have traveled extensively throughout China via simple tourist visas, there were no restrictions as far as I could tell, and I've never heard of any.
15 days is the duration for visa-free entry available to the citizens of the 54 "Western" countries. Only Singapore nationals get more than that.
The validity of a tourist visa is 90 days - it doesn't mean that presenting a 90 day itinerary is accepted upon application with a Chinese consular office. And as a general rule, it's not. If yiur itinerary includes any destinations outside approved areas, certainly not. As for hotels, see the following thread: https://www.reddit.com/r/China/comments/17fe0p9/why_do_lots_.... The vast majority of hotels will not accept your booking.
With all due respect, I don't think you know what you're talking about. =)
My personal experience as a Western tourist is that I could travel all around China for 2 months with no real issues. The provided itinerary was mostly a formality (and I didn't have to stick to it strictly). I managed to book hotels, trains, I even got a permit to go to Tibet (although a guide was required for that portion of the trip). It's true not all hotels can host foreigners, but in practice that's rarely a problem.
Although I personally wouldn't live there long term, China has actually a lot to offer as a tourist destination. It's very safe and there's lots of interesting history and beautiful nature to explore. It can obviously be challenging to move around without speaking the language, but some spirit of adventure goes a long way.
We're not talking about whether China is worth visiting. I think so, my tourist visa experience was in fact applying to walk a part of the Chinese Silk Road in 2019 with my (Cantonese-speaking but non-Chinese national) wife and we were politely told to shelve that particular idea permanently. There was no visa-free entry at all back then. We ended up going to Macao instead, and had a good time, though not at all what we originally planned.
In any case, the question was whether learning a Chinese language allows you to go on unique tourist experiences that would otherwise be unavailable. And the answer is that it doesn't, certainly not to the extent that it's worth learning a language, because, as you yourself state, you don't need to know the language to visit the approved destinations, and while there are some experiences that would require you to know the language, they are anyway outside the approved set of destinations and you'll be blocked using all bureaucratic systems from visiting them anyway.
I was also there in 2019 by the way. Out of curiosity, which part of the Silk Road did you want to walk? I can see why you would get denied permission to hang out near the Taklamakan desert.
