The issue is that there isn't a great alternative.
The euro is difficult to manage because of the diffuse control, pound an even smaller economy, RMB just not global enough (and tough argument to see that happening), gold/bitcoin/whatever not the same inherent stability.
Indeed the dollar weakening, but nothing really to take it's place.
CHF?
Literally cryptocurrencies are the single greatest alternative ever made. Opt out of the system where the government can just print money into thin air and old guys drawing dots on a plot set interest rates in closed meetings. If you want to hedge USD exposure just buy a Bitcoin ETF or if you really can't stomach cryptocurrencies b/c you don't want to be ostracized from the orange site, buy Gold. We are not going back to the way the world was and if you have all your money in USD realize you are on a leaking boat.
It is entirely possible to manage funds in crypto for growth and move some amount into more liquid USD denominated assets or MMFs when you need liquidity.
The ECB is not diffusely controlled.
