$119 or $139, not $200. It's also free via RMA if it was genuinely an accidental discharge. I've not had to replace one myself, but there's a YouTube short showing the replacement in what looks like 10 minutes, rather than a whole day - I've definitely spent more time shopvacing my floor after a project.

It's really not a problem because it's a reasonable safety feature, and I don't see any regulations that specify "SawStop". Harvey and Altendorf are making similar mechanisms, for instance.

Are you saying the government won't let you use a regular saw as a hobbyist, at a workplace, or with your employees? Those are 3 very different situations in my view.
