This comparison is absurd.That was actually my point with the comparison:
You don't have a right to blow cigarette smoke on others. Disney (as well as the government) can limit your smoking in public places, force you to limit your smoking to certain areas. Because when you smoke, you're affecting the health of nearby people.
For the exact same logic, people can be required to wear a mask when in public. Because when you go without a mask, you're not just affecting yourself, you are potentially affecting others nearby.
And I have found peer pressure (combined with govt and private policy) has generally kept smokers in line. Occasionally you get a jerk of lights up their smoke right in the middle of a crowded place. But that typically invites lots of dirty looks.
