Wow… did you wildly miss the point.

Occams suggested that each religious organization should register and own its own, unique name for whatever their analog for marriage is — this in response to the often offered objection that “marriage” is a religious term, and it’s somehow wrong to apply it to gay couples.

Sure, if you’ve got a sect that calls their ceremony “sealing”, and nobody else wants that, there’s no issue. But what if, say, an FDLS organization, excommunicated by LDS, were to register first, claiming “sealing” for their ceremonies, and (in the proposed system) legally barring LDS from using it?

That’s the issue — “marriage” is what Catholics, virtually every Protestant sect, Orthodox churches, and many others all use. If only one of them were permitted to register the term, barring all the others, to say there’d be issues is an understatement.
