They have the right to do as they please as long as they don't put others in danger.
This is the point though isn't it?
If, for example, a group of people want to party the night away - sans masks - in an overcrowded and badly ventilated environment, that's their choice. They may (or may not obviously) become infected.
Those same people are then quite free to travel on public transport the next day among others - without masks - among others who have no choice but to use the same transport. If any of those 'others' are immunosuppressed, have underlying health problems, etc, then they are at risk. Plenty of people who have health issues go to work. And even if they are healthy, they can still catch the virus.
So those who say "wear a mask if you are worried" are missing the point that the mask is as much to protect others as it is yourself.
Is it really too much to ask people to wear a mask for a journey on public transport or in a crowded supermarket? The obvious answer, judging by many of the comments on here and elsewhere is "yes". Because... "I'm fed up with wearing a mask"... "you wear one if you want to^... "I want to get back to normal". And our PM knows that he's flicking the right switch for such individuals because, basically, the elderly and health-compromised are an expendable minority to the libertarian mind. Ayn Rand lives on.
