Is it feasible to make each "family" or "lineage" responsible for itself?

You can copy yourself as much as you want, but you are responsible for sustaining each copy?

Could we carry this further?: legally, no distinction is made between individuals and collections of copied individuals. It doesn't matter if you're one guy or a "family" of 30,000 people all copied (and perhaps subsequently modified) from the same individual: you only get one vote, and you're culpable if you commit a crime. How these collectives govern themselves is their own business, and even if it's dictatorial, you might argue that it's "fair" on the basis that copies made choices (before the split up) to dominate copies. If you're a slave in a dictatorial regime, it can only be because you're the sort of person who defects on prisoner dilemmas and seizes control when you can.

Maybe when some members become sufficiently different from the overall composition, they break off and become their own collective? Maybe this happens only at set times to prevent rampant copying to swamp elections?
