Complying with all the ‘shoulds’ of self isolation at home are unenforceable and quite unrealistic. If you have a partner or children living with you, there is the hole in the Swiss cheese just waiting to align.
The only way it could be really safe is to have all household occupants also self isolate. The regulations are just so much window dressing. Without tracking bracelets, virtually useless.
Recently I had to self isolate after being in a hot spot. My wife voluntarily self isolated for the 14 days, even though there was no legal requirement for her to do so. Fortunately we did not have anyone else at home to inconvenience, but for those with kids it would probably make more sense to require quarantine away from home.
