That sounds pretty cool, but why not just make test when you enter? I think an isolation time of 3-4 days together with a corona test should be enough to guarantee that no infected people would enter the city. Also there needs to be some special procedure for all the delivery trucks coming into town, maybe they could be operated by some self driving cars and get desinfected before being opened. The concept is very nice and should used for some larger cities in rural areas where are not a lot of people visiting from outer town.
I would support fast testing however it seems to be failing at catching all cases we can see this with how new variants are spreading, South African Variant, British variant etc got here by plane and likely a missed case, so I went with two weeks.
I think there is also an argument for a month as sometimes the cases may be latent longer.
Assumptions in the above: (1) tests have 100% accuracy/recall (2) a 2 week period works for every single metabolism. Both false.
However, if the rate is kept at a minimum outbreaks would be manageable thinking Taiwan where they cell phone traced everyone and had those connections lockdown while using the quarantine hotels and New Zealand both did a good job of keeping a normal life going for them, even with a few Covid cases in the community.
In regards to a food supply, that seems to be the real issue I would say a mix of sustenance farming and decontaminating the food stock by shooting it up with UV lights etc would go a long way to keeping the isolation effective.

I'll add some other parameters that may be worth considering.
10% of cases are still contagious after two weeks
- You need the public to be onboard
- Need very clear guidelines and a two week rolling window
- Need high testing rates (tests are also inaccurate)
- Need effective contact tracing
-Need all levels of government to cooperate.
Small rule breeches can cause a huge cascade, for example there was one family that broke the rules and had 30 guests, and that nearly restarted the pandemic because one was infected from overseas. There are also all sorts of lobby groups that want exceptions to the rules.
You are in a constant state of having no herd immunity until hopefully the vaccine is effective and rolled out before someone screws up the quarantine more than can be recovered from.
However you have the advantage if it works of not destroying the economy and fewer people die.
Generally its a game of whether coordinators can overcome government screw ups and non-compliance.

Some of the breaches we have had:
1. Cruise ship shopped around all the different authorities until they found a person they confused and were given sufficient approval to disembark a load of people with covid-19
2. Staff at airports and for airliners had loads of exceptions and did not comply. For example if they were allowed to quarantine at home instead of a hotel but then just went outside and infected people.
3. Some German tourists as they were getting on the bus to go to quarantine told police they were domestic travelers and were in the wrong line then were allowed to run off.
4. People in lockdown in one hotel who had covid told security that they wanted McDonalds and were allowed to exit the hotel.
