You ain't the only one.
I think that this is just a big bluff. Unless the gov't winds up issuing credit cards (not THAT big a stretch, I'll admit), chasing away customers who want to pay is generally not the best business model for a company.
Of course, if gov't mandates something stupid....all bets are off.
They’ll likely try it, but scale back if they see too many creditworthy people stop/slow the use of their credit cards.
