I have 2GB fiber and can only get 250MB on WIFI. Faster speeds helps out with app updates, syncing/backing up photos etc. Especially noticeable on my PS5 when there are game/system updates.

Your usecase/situation is totally legitimate and valid, but I assure you it is not shared by 90% of the population.
If they have wifi at home they're using Comcrap (and the like) equipment that was set up for them. They have zero clue how all that works. And honestly, why should they? Most people really don't need to know. They just need it to work if they're paying for it.
