Right, but the people who need bitcoin most can't start saving until they have an honest unit of account that they can use for transactions where someone isn't stealing from them constantly by altering the account records.
If you are paycheck to paycheck bitcoin that needs converted back to fiat to spend will have to happen so fast you'll never profit after fees. If you can spend directly we just cut your fees in half.
I know you are thinking river or strike are 1% conversion fees. Great, you just spent 2% of income to not be able to hold long enough to make 2% in fiat gains. If you have never lived like that it is hard to imagine, but for a lot of people that 2% would be a full 2% more than they can afford. A one way conversion cuts their cost in half. Getting paid in sats make it go away altogether.
Or we may just be talking past each other because I was talking about the national reserve legislation legally defined bitcoin as only a savings vehicle and you missed that frame of reference.
