Money laundering is just illegal.
There are definitely legal ways too that screws you over in this financial world.
You say that you wouldn't want to live in a world where money laundering dominates financial activity? Well how about a world where cryptocoins/multi level marketing/ai stickers/private equity parasites/land owners (almost parasites?) /billionaires dominates the financial activity??
I guess you or many others live in such a system. I am not even talking about United states, I feel like to a lot of countries, the same thing is true.
