For me, yes. I like the duplicator transporter thought problem, but I've always come to the conclusion that it doesn't matter. If what comes out doesn't know the difference, and the version left behind just stops existing, what's the difference? Maybe if the old version suffered from it I wouldn't, but if they just cease to exist then what's the functional difference between the two? If you believe there's a soul then maybe there's an issue, but I don't.
