@ballexplorer: A good question is: If many people have to think about it.
I too have thought about it, even if it is still a long way off.

But after all, it is also a question of the conception of the BTC and therefore the question is justified.
With our current understanding of the BTC Blockchain, there will still be blocks in many years to be entered in the transactions and confirmed.
There will then be transaction fees for the miners.

@amishmanish: I like your thoughts on distribution and decentralization.
