It's pretty much the worst kind of house to have, enjoyable only by the ultra wealthy who visit every once in a while and leave it otherwise uninhabited. Having to take a fucking boat to get groceries or do anything sucks ass, saltwater-air is bad for basically everything humans make, etc etc.
I highly doubt it's even the world's shortest international bridge. Many nations' borders follow a tiny brook or stream, which will likely be bridged at some point.
they'll probably smugly point out that it's tongue-in-cheek and both island are on the canadian side of the imaginary line that runs through the st. lawrence river but it'd be kinda funny if some border patrol agents decided to wait on the "american" island to tackle and arrest the homeowner for illegal entry or something
Nationalism is a tool like any other and while there is some absurdity to it like borders broadly being an imaginary concept, we should not be cynical about borders existing because sometimes it does benefit the leftist cause primarily when it comes to indigenous sovereignty and land ownership among other things. Of course when it does not benefit us like the existence of every colonial country we should bring in the fucking clowns and make a joke of the concept. With borders we should act like it’s an old cartoon and whenever the border guard is not looking we quickly move the line further into their territory. Once the revolution is achieved we will look back at borders not with laughter or hatred, but with complete fucking indifference because it doesn’t matter.
