Isn't it possible to trace history of transfers in Bitcoin? I thought the blockchains contained information about transfer from and to account, and that's de facto the way to check account's value - by tracing it's entire history.

Yes but you will soon give up once that value hits a mixer/laundry, or an exchange hot wallet. No shortage of either.

but you never know at which point the coins came into the current owners posession. You could go back 1 step or 100 steps and trace the coins linegae from their creation until today but without knowing who owns all the intermediary addresses youy dont really know anything other than how much was sent when.
