Nothing stopping you from making up a physical address. As far as Name Cheap is concerned, I live in New York (I do not live in New York). In theory* "they" could revoke your domain, but, in practice my oldest domain is 28 years and still mine.

This works until it doesn't. If ICANN receives a report about your domain, then Namecheap will be contractually obligated to investigate and suspend/revoke the name. https://www.icann.org/resources/pages/inaccuracy-2013-03-22-...
