Plenty of people live on boats in the UK. Some boats can be fancy AF. Or very cheap. UK has an advanced man made canal system covering most of the country. The water is still there, there are charging stations, toilets, gas refills, etc available to boat dwellers. Canals were previously used for goods transportation across the country, but now we have trains, trucks and planes for that, so canals are now used for living and recreational travelling. And fishing ofc.
