Which copy wins the philosophical claim of "being" "me" doesn't worry me.

Which one wins the legal claims of "gets to lock the other copies of me out
of the house I'm living in now", "gets to continue the relationship I have
with my employer right now", and most importantly, the social claim of
"gets to hang out with my unduplicated wife and kids"...

These worry me a great deal. Enough that I think I'd like to have a good
plan in place to resolve those claims before a hundred (or a million!) of
me wake up one fine morning each having a 99 (or 99.9999!) percent chance
of being disposessed of unduplicatable real property and relationships and
we have to start playing Highlander ("There can be only one!").
