Possibly, since I have no such things in my life, and am very unlikely to ever again. And never truly had them in the first place, in all likelihood. My personal belief is that life is a conditional good, meaning that under such and such a set of conditions it is worth continuing to live, and that failing those a voluntary death is both a reasonable and rational choice.
BTW, the downside to having such a thing as "friends and community" is that I'd likely feel quite a bit more guilty than I do about ending my life through suicide than I currently do. If I knew for a fact my death would affect fifty people rather than two or three I'd probably still proceed, assuming that's how things end up, but I'd certainly feel guiltier about it.
In my case, though, the whole business would never leave the realm of the hypothetical. I'm without doubt one of the most unlikable human beings who has ever lived. Not in a mean-spirited or evil way, just that I'm too selfish and too blind to social cues to really have friends or belong to any sort of community. Stopped trying some time ago.
