No? That's literally how banks work. You store your money there, and they protect it, manage it, etc. But this isn't harry potter, there isn't some underground vault with your name on it, they just take all your money and stick it in a giant pool they use to invest and make themselves money.
'Your' money is actually just them tracking what you actually have, and if you ask for some of it, they have the equivalent of petty cash they pay it out with. You cannot pull out massive amounts of your own money all at once without warning on the spot, because they simply will not have it available.
It's why depressions and 'bank runs' are a thing- the actual amount of cash a bank has on available is ALWAYS lower than the total number of assets they have earmarked from people, because it's all tied up in investments. If those investments go belly up, or everyone all tries to pull money out at the same, the bank has a major problem.
"Freezing" someone's assets just means that the bank isn't allowed to let someone pull money out, or transfer that money, not that the cash/investments/etc are pulled back and stuck in a vault somewhere- the BANK still has that money it's larger money pool, because it was always there from the first moment they got it.
To be entirely fair, what civil discourse can you have around "We want to make bloodsport of murdering these people." vs "Maybe just let people have basic rights."
