In my opinion personal behaviour is the -only- problem.
Seeing the number of weekend travellers from Bangkok to Chiang Mai since it was allowed again, it is clear that people show very little responsibility or self-restraint. Grabbing a beer in a bar or satisfying your desire to get away for the weekend can wait until other people can feel as safe as you.
The ones that do this are privileged to have been jabbed. If the shoe were on the other foot and others were taking liberties while they still waited for a jab, they'd be saying the same!
Unvaccinated people pose a greater risk to the general population and the availability of health services, as ExpatPattaya stated. That reason alone is enough for their movements and interactions with others to be restricted.
"Vaccinated people are not as likely to spread the coronavirus as the unvaccinated. Even in the United States, where more than half of the population is fully vaccinated, the unvaccinated are responsible for the overwhelming majority of transmission.
To spread the coronavirus, you have to have the coronavirus. And vaccinated people are far less likely to have the coronavirus—period."
