I know the potential "problems" in the article but I've never encountered them.
Literally never.
I'm actually quite surprised that people still have problems with wireless devices in this age.
Even if I had a desk, I'd probably only plug my laptop to prevent battery cycles (and to keep ready for when I wanted to move) but would never bother with Ethernet, or a wired mouse, or headphone jack for example. Any additional latency/performance problem is imperceivable for daily tasks (unless I am a professional esports gamer or trying to download a huge blob over a gigabit connection as fast as possible, which is probably not 99.9% of people do).
You basically say that you don't care about latency/performance loss, but are surprised that people still have problems. Maybe because these persons do care?
While downloading/uploading something there will be no practical difference between Wi-Fi and Ethernet unless you are on a superfast Gigabit fiber.
While on a Zoom meeting the latency introduced by Bluetooth, while slightly perceivable, isn't of an issue over the latency of being connected over the web itself.
Any wireless system would have more or less be less performant than a wired equivalent. What I'm saying is that for 99% of the people in 99% of daily use cases, that difference wouldn't matter.
I have about a 300 Mbps connection with my ISP. The gateway/AP provided by the ISP is located on the second floor of the house. On the first floor, the connection is degraded to the point streaming will occasionally stutter.
On the second floor the difference in speed tests going through cable vs 10 ft. away through one thin wall on my gaming pc is 250 Mbps -> 24 Mbps. There can absolutely be a practical difference in daily use.
Most people do not have multiple APs, most people are not getting APs other than what is provided by the ISP.
Well the problem is your access point, not a vague 'wireless'. I can max out my internet connection through a couple walls. And while I had to get my own AP, I would have had to get my own cable if I wasn't doing wireless. They didn't include any that can reach between rooms.
Multi stories have that problem (probably because of the shape of antennas designed), it can be easily solved by a gigabit ethernet cable and another AP.
While definitely not ideal, it's a solve-once-and-forget problem.
Literally never.
