If you can be prevented from spending the money in your bank account, is it really your money?
Not sure about your fiat but in UK, 'paper' fiat has "i promise to pay" on it. An iou in effect. Thus, another marker that's not yours.
You money in your bank: 1) aren't yours (it's IOU) 2) aren't money at all (it's fiat currency, not money) 3) it's not even a bank (it's a goverments service, run by "private" cronies) nostr:nevent1qqs2m4n32f6k90gsz50z0r4ezafscn6dlne3fed03pg7p4n2240xyqcppemhxue69uhkummn9ekx7mp0qgs8hxglwaksfkrukh2zt95grpa9yrm2lstt9wddymdvdw8wwmpggrgrqsqqqqqpfdr45z
