I like that place. My wife's eyes lit up when watching the clip as well.
As I've never lived on the water though, I'd be interested to see how bad it is for midges and mosquito's during the summer as well as how thick the ice gets during winter.
Really thick ice would stop their boat but be OK to walk on I assume but I wonder if there's a thickness of ice that stops the boat but is still too thin to walk on?
Some of the off grid retirement homes are great but people buy them when they are getting on a bit. Its a bit like people buying a house/cottage in the country when they retire then they spend a fortune on getting it converted for the fact that they might be losing mobility. I see it a bit in the building trade and sometimes people get the house moved into then shortly afterwards they can't cope and have to move out.
In short, I really like the place but suspect its not the best setup for the elderly.
