Of course you should get back from the thief's what they have stolen from you and the other people!

I'm not advocating the opposite ( I speak for myself here because that's the only person I can speak for or from) I'm also not responsible for the ponzi scheme others have put in place and am not guilty of the theft of those billions. But that I say I can't do anything about it or have a solution to get the money back is not the same as advocating the thiefs to get away with their billions.
It's saying. I take my lost and I'm gonna be free from now on and let others be free.
I don't (or even can't) find a solution for the problem that I did not create. And I believe noone can. Except, if you don't advocate for governments or masterplans or mechanism which force everybody to do something under the threats or violence in the future.

Maybe this analogy helps, Imagine the "cotton slaves" that want to be free but other slaves telling them you first have to take care that we get our cotton back (or the equivalent), before you can be free, or else you are for neo-slavery. Then the slave that want to be free is made responsible for what the masters have done and stolen.
The other slaves want him to solve the problems of the slavery and theft in the past before they"can let him be free" which means they keep him as a slave and they are the master that can decide to let him be free as he has done as they dictated
In this analogy the slaves surrounding the "slave" (free man or woman) are his or her master, they may not see it but they are keeping him or her enslaved.
