a somewhat unfortunate example, since alcohol is very easy to make.
All you need is some fruit(juice), and maybe some bread and sugar. -
but that aside

Well, not by limiting freedom of religion, preferably. I suppose it
would depend on how many people in the concerning region would want to
get rid of the prohibition, and how badly.
If several percent of the population would stand in line to emigrate
because of a certain prohibition, the nation would have a serious
incentive ;-) to make provisions, or the world govt could stimulate
that it make provisions.

It depends on what you call "communities". In the netherlands it's up
to the municipalities to decide wether and how many legal
cannabis-retailers we have. Of course this is also limited to
economics - the amount of users. If a village consists of 99%
vegetarians, any butcher-shop there will go bankrupt, unless its
compensated by tourists.

Does anyone have a trickier example? I mean , female genital
mutilation (sometimes eufemistically referred to as "female
circumcision") is a horrible thing, and any female volunteering for it
has a severe mental problem (well, transgenders excluded, maybe).
Point is, you won't find a thousand people of voting age volunteering
for it within one municipality

That's why freedom of association,assembly, and of opinion-expression,
are so important. So people can find out how popular (or even
plausible) their views really are.
Similarly important is the right to leave your region, tribe or even
family, so you don't have to stay locked in a regime.
