You're correct that the cap on Bitcoin is somewhat arbitrary, but the point is that there IS a cap, which is not the case with fiat currencies which can be printed indefinitely (which is why the purchasing power of all fiat currencies goes down over time).

You're incorrect to state that crypto is "controlled by a much smaller number of unaccountable people" -- Bitcoin and Bitcoin Cash are decentralized networks with lots of different stakeholders (miners, developers, exchanges, wallets, users) and no single group is in control. Quite the opposite -- there has to be broad consensus among all the groups for a cryptocurrency to survive long term. Not possible to fork your own currency off of the USD or the EURO!
