I think a fair way to put it is that for most of us on this board, we like trains, but we also like being alive.
In my case, I don't ride because, again, I quite like the whole staying alive thing, but also because I live in a country where it's completely impractical. If I were to hop on a passing freight train, I'm not going to end up anywhere useful. It'll be the local coal-fired power plant or the steel works further down the line, neither of which sound like particularly fun places to be without supervision and PPE. They're also fully fenced in, which is a legal requirement of both the network as a whole but also any connected facility.
