Similarly, because 95% has been mined, I am not so sure that people will use bitcoin over an altcoin as a means of p2p transfer. It's supply in 2024 will be far too small to facilitate hundreds of million of people buying in to actually use it. Because by 2024, either the legacy rail has taken over and bitcoin is far too expensive relative to it's supply OR, it will not have happened and bitcoin will be worth nothing. Perhaps this is too simplistic an argument to make, but 10 years is not actually very long.
It didnt use to concern me, but it does now.
It concerns you because you think outside the myopic delusional bubble that is bitcointalk and /r/bitcoin, and thats exactly the reason Monero or other more suited and permanently disinflationary coin for p2p payment will eventually take over, you cant force people into one (public, transparent, NSA-stamped) blockchain.
