Bitcoin solves this. Clear, unambiguous, unchanging monetary policy that doesn't constantly increase the supply and take a portion of your dollar's value to give to anybody else. It is not aligned with any country or even block of countries and is truly the first international currency in that sense. No politician or even national or supra-national government can force Bitcoin do do anything that isn't part of its protocol because it's so decentralized.

It has been running 24/7 365 for 15 years without a single major security issue in the protocol or a single hour of downtime. With lightning network upgrades, transactions confirm in under a second internationally with fees 1000x less than credit cards, often under a single cent.

It is accessible to anybody in the world with a cell phone and internet access, including the billions, with a B, who don't have access to stable banking infrastructure or local currency. No credit checks, no needing six forms of ID, no overdraft fees, no bank holidays, no middlemen, no nonsense. And it does this with less electricity than you'd think, less than 1% of global electricity usage, mostly from renewable sources as miners chase the cheapest electricity and the cheapest electricity is from renewables and over-provisioned grids.
