If such thing happens, it's just the ruler being hypocrite or minarchist. And me, being minarchist would only take taxes from bussiness leader thta currently have employees or someone who needed a public service in cases of urgency
an example:
> anon needs surgery
> the minarchy inmediately pays for it, since they own the money, the most powerful media and technologies
> anon is taxed by paying the loan to the state as long as he has a job
> if he cannot find a job, the state gets him into a labour camp for non-convicted individuals
> when the debt ceases, anon returns to being untaxed
