If the price is high enough then big mining farms will continue to dominate. Make no mistake about it. If having 1 miner makes you $1 a day then having 1,000,000 miners will make you $1,000,000 a day so if you have the money you buy as many as you can.
If you cannot make money then the larger miners are going to go away and mining will come back to the home.
If I loose $1 a day but I enjoy mining bitcoin then guess what I am going to keep mining it with something sitting in the back room [So long as I can run it on 110v and it's quiet]
So, it's not "For how long can we actually mine ?" it's how long can big miners keep mining. For people mining as a hobby or for fun, making or loosing money is a secondary consideration.
Just my view.

I will always mine. but your point here is very valid.
my estimates are 2025 or 2029 and big mining ⛏ ends.
transactions fees do not scale past those years. I personally don’t see btc at 50,000 levels for lots of reasons. basically any clone of it will do as long as the clone uses sha-256 since this is the most common gear.
