if you become the ruler, please grant me the sole right to sell those signs that would indicate the businesses catering smokers.

I will be damned rich because every single business would simply buy a sign and go on as before.

Thinking of it "Smokewhiner`s" would be a great name for my business...

Apparently publicians are to timid to try). Nothing especially wrong with that: every market needs its regulations to work properly - otherwise trusts would take over and establish a monopol
