I might be missing your point, can you elaborate? If you want to write an if statement you just do it at the end of a component, after the hooks. It's a common pattern.
Web libraries don't update more or less quickly than any other platform. The "issue" with web is the pace at which new frameworks are released but at this point even React is over ten years old. It's not that bad. Things are more stable than they used to be and new concepts are quickly adopted by each framework so you aren't forced to switch to something new, see for instance signals.
In a world of Verblen goods, which includes $30,000 more-esoteric-than-Rolex watches, what does "worth" even mean? It's not like there's a vibrant market for Internet businesses that underpin online communication to discover a market optimal price. Musk wanted to buy Twitter, and wanted a discount. He threw whatever language he could at it to try and get the price lowered. It's not like you can go to the store and buy a Twitter or Discord. You have to haggle to come upon a price that both parties can agree on, which is a foreign concept in the western world.
Things are worth what you're willing to pay for them.
