No business has EVER survived doing purity tests about the money they accept . There have ALWAYS been multiple monies. You think we would be using gold or even silver in 18th century France for daily purchases? No, we were using several dozen different blackened bits of various metal at confusing exchange rates. The maxi ideal of "all money returns to one" is just another retarded doctrinal point that maxis accepted without understanding the actual complexity of the systems involved.

then don't complain about a failed business after intentionally limiting your customer base.
