I say no, really. Like, yeah, it'd be cool and all cause science, but I highly doubt that clones would be given the same rights as non-clones. They'd be treated as sub-human, especially if cloning becomes commercialized (for some reason), where they'd be imperfect clones and such.
I just don't see a good reason that doesn't basically treat the clones as sub-human expendables?
What I think it will be used for is war, sex-trade, slavery, etc.
There is the possibility that each person could simply be cloned for immortality purposes; that is, having a stock of clones on standby that will replace you when you die and just have your memories transferred over. But that's not REALLY immortality, because the old you would still be dead.
But then again, no one is actually really alive longer than a second. Your brain is constantly disconnecting and reconnecting, and you aren't the person you were five seconds ago: that person is dead.
Back on topic though, the "immortality" thing would probably be reserved for the extremely wealthy (supporting a stock of clones on standby constantly costs a lot of money), which calls more ethics into question? Mr. Bill Gates here gets to live forever, while Mr. Middle Class only gets to live 70 years.
tl;dr cloning has no good reason that doesn't mistreat clones themselves
which is kinda gross
Also, cool the heat guys. You asked parquette his opinion and he gave it, don't go all super-offensive on him.
