Unfunny punchline attempts aside...


quite simply "many are called, but the chosen are few"...not everyone who claims to exercise this power actually wields it. False prophets are everywhere.

Additionally, those who do, have limited power to bind Satan...that is, they bind him in that limited instance (personifying a crippling disease as Satan, for instance) and not in absolute entirety. As I said Earlier...Satan is very much part of the plan, so he has to be allowed to 'do his thing' within limitations.
