Not sure how well I would hold up.
Food might be a problem. No restaurant delivery in my part of the island - but I would get on the phone and beg the Italian restaurant down the road to work something out. Might have to work out a deal with one of the hotel employees to drop off dinner on their way home.
The Australian and Indian-Chinese fusion places already provide a service to pick up diners from the nearby hotels, so they are driving right past my house a few times each night. I think I could work out a delivery option from them.
As for providing my own food, if I am allowed to the boundaries of my property then I would cast out some fishing lines and hope for some seafood. Gardening might not work. Sandy soil and salt everywhere. Coconuts only go so far.
And there is a guy who offers a service to do grocery shopping for tourists to stock their vacation homes before they arrive. I suppose I could pay him to do my shopping, but he charges quite a bit for his service.
I’ve had an idea for an idea for an internet business for some time now and would have to give it my full effort to try to make a living. But I would need someone to assist, as the business idea would require having someone taking pictures around the island on a regular basis. If I couldn’t make this work I would be in trouble financially.
I would have to depend upon the visiting nurses from the Health Services Administration for medical care. Unless I have an accident requiring more complicated treatment then this should suffice.
In reality a part of my job is to monitor persons placed on an electronic monitoring program. Most are free to leave their homes during the day, but a few are on 24/7 restriction. And the large majority of those on 24/7 restriction are fully compliant. So it can be done.
But there are common sense exceptions where such persons can leave their home for genuine emergencies (house is on fire!), necessary medical treatment (scheduled appointments and/or emergency transport as need determined by ambulance crew consulting with doctors at A&E), and to go to the court for their legal proceedings.
