The healthcare costs are indeed unfortunate, but personally I can't think of many things that would be so dangerous about chainsaws.
Kickback will happen with every saw, the chain brake should be tested before every run anyways. A 50cc single cylinder engine doesn't feel like it'd be too dangerous to be around, especially with the rest of the chainsaw body around it. Maybe the chain wouldn't be too good and people would tension it too much, or perhaps it could come apart or something. Even then, PPE that you're wearing would generally make you safer. Realistically, at most it won't last you a decade and signs of wear will become apparent a bit earlier.
Regardless, I get your point and thank you for making it!
