Forcing people to vaccinate is not really a tool to control infections right now, and more of an independent (also currently hotly debated) longer-term question. (I'm fairly certain its going to come for some jobs at least)

And if applied as here, I doubt many would argue that "forcing people to vaccinate" is a weaker measure than "impose some restrictions on unvaccinated" (although the former is of course going to be a strong form of the latter)
