I guess that's debatable, but I'm reluctant to say that a $2 fee is acceptable for a cup of coffee. That being said, I think Justin Bon's is saying that as the amount of rewards per block decrease TX fee's will continue to increase and must replace the miner's revenue from mining blocks otherwise they will exit the ecosystem. Current block sizes and a reduction in miners producing blocks will also increase TX fees?
I wonder how much exactly the miners spend to mine Bitcoin and verifying the transactions, then how much they actually earn from that, so we can get better illustration what he said is true or not. We can't just look at the miners revenue graph which continue to drop, because it was rise so high due to ordinals.
I'd say miners will be more centralized, small miners will leave (many already left) and they will move to country where electricity cost is cheaper.
