When I first read the Rik's post I thought it may raise some 'interesting' replies, but to be honest there seems to be rather a lot of muted hostility against anyone that dares go against the grain, or pose these sort of questions. As someone mentioned above it's forum, where people come to communicate and exchange ideas. Part of communication is asking these sort of questions.
For me, Bushcraft or Re-enactment, well it's fairly simple. I don't use Iron Age gear or the likes, so it's not Re-Enactment. I use modern gear, maybe it's designed on old ideas, but what isn't. Maybe it's been made by me, or not. Each to their own. If you like old style kit, great - I think it looks great, I mean look at Waylands outfit, old style and functional - that's re-enactment when he's working. When he's just being him, it's just him. I use Wayland only as an example as everyone one here knows him / of him.
However, that's not addressing the original example, to which the OP has already answered himself. People take what kit they find either most useful, easiest to carry or maybe it's the only kit they have. I often see people driving certain cars and ask myself why on earth would they buy that, when every review out there slams it for x,y and z. Who knows? Maybe next time if I spot someone getting out of one I'll ask.
These sort of threads don't bug me really, but sometimes the general feel of peoples replies do. While I agree that everyone has the right to respond as they feel fit, it would be nice if these things didn't degenerate in to sarcastic or ironic responses and actually offered constructive input.
