Fortunately we have these things called "courts" that are able to apply reason and nuance in combination with logic, with human beings called 'judges' that are able to comprehend a difference between someone who went out to dinner and someone who locked a broom closet to try and falsely claim residence at a property.

You're not the first person who has tried to falsely claim residence at a property, it's a very common way to commit tax fraud by claiming homestead exemptions. The courts won't even entertain this sham for a single second.

The point is, if I AirBnB out my place while I go traveling in Europe for 6 weeks, it's perfectly clear that I meet the exemption.

If I buy another structure and AirBnB out that place, it's equally clear that I don't.

Yup, temporary absences like vacations are perfectly allowable. You just can't say that you reside on a property because you locked up a broom closet, even though you never live there.
