Do tax havens defend free markets?

Tax havens rig the market in favour of a small number of players at the expense of the rest, essentially eliminating market freedom by making it impossible for everyone to participate. Tax havens allow money gained elsewhere in the world through illegal means (such as bribery or drug and human trafficking) to be laundered and flooded into markets, causing prices for things like real estate to be artificially inflated due not to genuine demand but for the need of criminals to park their wealth in assets while concealing their identity.
