I don't think I could recommend to someone I care about that they put themselves at risk the way most providers do. It has nothing to do with "morality" - it's just that it is a dangerous profession and anyone who participates is taking a huge risk.
Now, if it was legal and respected most places and someone really enjoyed doing it - why not? I have met providers who clearly loved what they were doing, others I'm not so sure about and a few who clearly didn't want to be there. Unfortunately, desperation makes people do things they probably shouldn't be doing.
And hobbyists take a risk as well, although not (it seems to me) as big a risk as providers.
Still, if someone I cared about loved doing it and wanted to do it - I would support them and try to help them stay as safe as possible.
