government will collapse with its banks, question will be there who will make the laws
gays? criminal thugs? warlords?
You'll have to experience it too see how it plays out. There's no way for a land to exist without some form of a government, unless you want your area of influence to decrease, or you don't want to have land at all and live like nomads.
lawyers are nowadays highly corrupt individuals, it would be better to find a way somehow arround.
Don't generalize. There are honest lawyers, just like there are good policemen and so on.
Lawyers have to be witty to go around stupid laws that some idiots came up with in the first place and nobody has the balls to remove.
before you build it, ask yourself, can I get the liquidity?
Yup, it all starts and ends with money. You can always start with something small and local and slowly expand, but it will still cost a lot.
