If that would be the case, won't there then be the risk of creating a short-circuit which would benefit the actual money launderers/criminals?

Say, I have 3 millions somehow deposited in the $bank_where_i_put_my_shady_money, I want to take/move the money, but doing so will raise some eyebrows, so I deliberately try to debank myself so that I can get all my money cash OR move it to $partner_bank

Possibly. All I'm saying that what banks do isn't simply "firing customers".
