Next time someone asks me why I don't like state licensing of businesses and trades, I'll point to this story.
The hero, one Mary Jo Pletz, was investigated by PA state officials for running an eBay store without a PA state auctioneers license. The situation was summed up brilliantly by Barry Fallon, who was similarly investigated by PA's bureaucrats:
It's like the buggy-whip manufacturer's deciding whether these newfangled automobile manufacturers can do it without a buggy-whip license.
It's wrong, plain and simple - in this age of easy, instant, and world-wide communications and commerce, PA foisting their licensing scheme on a global business makes no sense.
Remember, you voted for these people - call them and tell them what you think.
