Even if someone believes that it is inherently wrong for the government to enforce some moral behavior, that still doesn't absolve them of the moral requirement to perform that moral behavior themselves. That is to say: it would be different if someone said "I think it's wrong for the government to force people to quarantine; however, I'm going to quarantine anyways because it is the right thing to do."
