The practical mechanisms to handle stalking like this are restraining orders and trespassing laws. Trespassing is the easier of the two to utilize. If it's your land, you can tell the police who's allowed on it. Once either of those things has been set up, the police can arrest the offender the next time he shows up.

Beyond that, move somewhere with a strong castle doctrine, where you can own a firearm.

This isn't a new problem for societies and there are good solutions, which have been eroded over time. If you can't shoot intruders in your house without consequence, you are living in a failing state. If the police can't be relied upon to keep repeat offenders away from you and your property, you are living in a failing state.

What nonsense. I live in Japan, where it is practically impossible to obtain a firearm. The same would be true for the OP in Scotland. Neither should be considered a failing state except under your ridiculous definition.
