Stupid question - turbo spool-up

OK, this is probably going to sounds pretty dumb to you guys who really understand turbos but here goes. Other than the obvious wear-and-tear issues, why can't we keep our turbo spooled-up all the time? My thought is this: an engine-driven air compressor feeds into a fitting in the exhaust side of the turbo housing. The compressed air (pick your PSI, I haven't thought that much into it yet) "blows" on the blades of the turbo when there's no exhaust pressure, keeping it spinning all the time. Maybe mount a sensor to cut off the air when there's exhaust pressure? Yes? No? I'm not about to go drilling into my turbo just for fun. If this was viable I'm sure someone would have thought of it already, but I figured why not ask the stupid question?
Embarrassingly,
Darel
