Even if it were true that "Randi always has an out" it would be relevant only if Randi were the only person willing to entertain the notion of doing these tests. If someone truly had abilities they could show them and if they showed them over and over to many testers and they worked for everybody except Randi then (a) Randi would look like a fool and (b) Randi would be irrelevant. Of course, having a dozen woos certify you and then losing to Randi doesn't qualify as true proof because you didn't test with non-woos, but there are lots of testers in the world besides just Randi and woos.
Indeed. E.g., the Danish skeptics sure aren't inundated with paranormal claimants, even to be tested while not applying for the JREF million.
