Not easily that's for sure. Although, I get it not everyone cares about relying on a third party, my concern with OP's suggestion was purely on it being mandatory, since that forces the user rather than giving them the choice. There will be people using Bitcoin for different reasons to the third party concerns, and some will be comfortable with it. Personally, I wouldn't be, and I wouldn't advocate it, but I do understand that some people would actually prefer it. If we want mass adoption, then that's the reality of things, and depending on that individuals circumstance, could actually make some sense.
