How can you possibly build a tuner that tunes and decodes every possible system that wouldn't double the price of a TV set? It might have been possible if the US used the European DVB system but I am not even sure how compatible each of the variants are with each other (DVB-C for Cable, DVB-T for Terrestrial, DVB-S for satellite).
The closest thing I could think of is a system based on IP (with common compression and encryption systems) and you would have to buy the appoporiate PHY (physical layer) module to match up with your delivery system / provider. A QAM PHY for cable, an ATSC PHY for OTA, a Verizon PHY for FiOS, etc.

It would probably work exactly as you describe, for the reasons you outlined.
If they really wanted it to happen, they'd make it happen.
