In a way, I can understand the problem and I do sympathise ... But {there's always a but} one size does not fit all.
My [late] father owned a home near Porthmadog jointly with my brother - but not me [I own my own home, in Northumberland].
When Dad died, the house passed into the sole ownership of my brother.
Currently, he lives & works in Birmingham - where he rents a shoebox aka a ground floor flat.
However, he still spends almost all his annual leave, and many of his rest days - when his work pattern puts more than three days off together, which happens at least once every four to five weeks - working as a volunteer in various capacities on a certain North Wales Narrow Gauge Railway ...
Sadly, that commitment doesn't matter to some of the anti-second home owner rules and the only place he actually owns is classed as a second home because he doesn't spend quite enough nights there for it to be his full residence.
He also does his best to support local businesses and shops. He buys food locally etc etc.
Unlike some 2nd home owners / Airbnb visitors who stock up with food before they travel - what a way waste of fuel, lugging all that weight with them ! Especially as there are several well-known supermarkets in Porthmadog, Pwllhelli and so on ...
