You could do what I did:
- only buy a house in a place that has no HOA
- xeriscape the front, let most of the back just grow out wild, and keep a small patch of grass in an area where you like to chill (for me this is in a courtyard)
- use an old school push mower for this small patch. You get a little exercise with this, but not enough to ever stress ya, and it requires no gas, no oil, no electricity and barely ever any maintenance.
Historically, more often than not, when a narcissistic megalomaniac is victim of a close call of targeted violence against them, rather than them becoming more empathetic with the sadly large swathe of humanity that also often faces targeted violence, they just double down on their own paranoia.
