Whut? Apart from all the redundancy in that one sentence, backwards you have it. People would avoid the business. He'd go bust. So it's a democratic democracy. Not an autocratic autocracy (the whirring noise you hear is old Chalky Evans, my old English Language teacher, spinning in his grave).
Include the whole post (especially when short) or at least the whole context.
You: I don't know what people are like around where you live. But people in these parts are queing to get a jab. And if a business stuck a card in their window saying 'Not vaccinated now, not vaccinated ever' then pretty soon there'd be another sign stuck over the first saying 'Property for lease'.
Me: "Ah, so you live in an autocratic top down autocracy. There are several of them: California, Michigan, Oregon come to mind.
Around here, no one would put such a sign up, nor would anyone inquire, much less a landlord."
Reality:
About a third of the population would avoid the business from such a sign saying the owner wasn't vaccinated (though no one would actually do this, or very few) - the autocrats who think, despite all rationality, that if they can avoid the presence of the "undesirables" those who have not taken the jab (even if they already had Covid), that they are "safe" from contracting or spreading the virus, which we all know is abject nonsense, as even the CDC has admitted, and the rising rates of hospitalized vaccinated are proving it out.
We are way early on too.
The other 2/3 of the population would shrug their shoulders and either do business there or not, depending on convenience, because they were either 1) already recovered from Covid, believing they have immunity, 2) received the jab, and believe they have immunity, or 3) will just wear a mask to be safe as everyone did the past year and a half.
They don't live their lives mandating what others must do.
