This is a wonderful idea. Is it really possible to claim a place in international waters? I have never heard of the possibility of it. If anyone happened to find the photos of the mentioned seastead, please post it here. So, others could get a better idea about it.
Well according to this article nope I guess because the lady lived in Thailand she was still under Thailand law, but in theory in Canada if you laminated your birth certificate it becomes void it actually says it right on it. So you would not be a Canadian citizen anymore. Then you get on your "BIG BOAT" I guess if you call it a seastead? there is a problem there? and go out to sea, live in peace, not forced to pay tax to any tax man, but perhaps create a society on the island that the people are willing to give their tax and all vote on where it goes, instead of voting people to vote for them, stuff like this would not happen.

You will also be in a good spot for when mass flooding happens. You will just float on top like noahs ark or something lol.
You can`t "Claim" it btw, but you can live there, but if you do not want live by international law you don`t have to, you might want to make a military then. You do not have to sign the treaty.
