It doesn't make it any less-region

But what exactly is your point?

38.1097387° N, 13.3520066° E

What's their point?

Because Sicily has a President, an offer to them that can't be refused, can be made. Can a region sign contracts? In this case, yes.

lol "president"

I have a president in my neighborhood's polka club too.

At which point, your neighborhood's polka club can enter into certain kinds of contracts on behalf of the members. Same as the region of Sicily.

Sicily has over 4 million inhabitants. Probably the budget of your polka club is slightly smaller.
