The distinction is consent. You would need to get meaningful consent from everyone present when you walked into a store without a mask. EDIT: Actually not quite. To elaborate a little further - it has become understood that it is just and reasonable for the state to have jurisdiction over interpersonal interactions that involve money (though the converse is not necessarily implied) - this is 'the market'. Thus going to the store operates under a different regime than going to a friend's birthday party in their own home. Your example would equate to the state mandating condom usage with prostitution, assuming that was legal in the first place. What you get up to at the store can be regulated by the state - what you get up to in the bedroom (without financial exchange) should not - assuming meaningful consent
