If I were you, I would stay in NYC and try to stay as clean/isolated as possible.

If the theory that people who already got covid19 develop immunity from it and won't catch it again is true, then one thing to realize is that NYC (and Italy and others) will become a "safe" place sooner than other places. Yes, there's the horrible downside that a lot of people are dying, but since so many people already caught it (and so many will catch it in the next days/weeks), after this peak passes you'll reach a point where mostly everybody around you will be immune, so you will benefit from herd immunity. If you move to another city, one where the number of cases is still increasing, it will likely take longer for this stage to be reached.

I should note that I'm not advocating in favor of society pursuing herd immunity strategies: letting people die is never a good strategy. I am just pointing the fact that the since the curve is not very flat in NY, herd immunity will be a thing there sooner than in other places. It's happening whether we like it or not.

I'm not a doctor and I'd love to hear arguments on how this theory could be wrong.

There is evidence coming from China that people who had the virus and recovered became re-infected. Which means there is no certainty at this point on immunity.

I am aware of that, but there is still doubt in that data. Apparently the tests used in a lot of Chinese people have really bad false positive and false negative rates, so it could lead do conclusions such as apparent reinfection. We'll have to wait and see if it happens with more people, especially in regions with more accurate testing.

Do you have data sources?
