That’s even easier because they are technically fungible as well as legally. It is possible to say this $100 bill was once stolen so we are going to seize it from you even though you are perfectly unrelated to the crime and just happen to have ended up with it. The law treats money specially and prevents that from happening, but otherwise it could. It can happen with something like jewelry or a car. With electronic money you don’t even have a practical option even if there was one legally. There’s no specific hundred dollar bill to seize. Banks don’t track with that kind of granularity.
