Maybe you're right. Myself, I wonder if the behavior that I
expect people would exhibit in thought experiment scenarios
is accurate. How, for example, would they really respond
to proof that they were "merely a copy"? Would two
copies automatically fear each other and try to exploit
each other as depicted in the recent movie "The Prestige"?
(I very much doubt it.)
What is different about this philosophical dilemma and the
traditional ones, like the one concerning the is/ought distinction,
is that conditions may rapily change from what they are now:
we may, before too many more decades, find it quite
possible to have copies (especially in uploading scenarios).
It'll be interesting to see what happens, if you and I can make
it that far into the future.
