This is becoming thread drift now.
underfire, I could also make a good argument to put WAAS over the continent. Think about it, ASA owns half of that system...do you really think they will fit out a basin and then allow use of that same system for gratis?
If the argument is saving lives, you only have to think a little where all the fatalities have occurred...we should start another thread and bring this one back to why would someone want an exemption to fly in controlled airspace without a transponder.
