I guess people stealth camp for other reasons, but if it is only to save money it is seldom necessary. For me hiding out in the woods isn't what touring is about. I'd rather be in town where I meet the local folks. As a result I'd only stealth camp in a pinch.
I like stealth camping for the quiet, on the outskirts of a town, in an area that may be farmland, public right of way, state forest, etc. The money I save, I use to meet the locals over coffee and breakfast, or lunch in a public park, etc.
