International law is complex. Having a full-time employee located in another country can lead to a lot of legal unknowns. At the very least this requires a company to spend the money to understand if they are exposing themselves to any international laws that are unknown to them. I am not a lawyer but have run businesses in the past and legally that would scare the hell out of me. Also, benefits were brought up by the other commenter but it wasn't addressed in the legal context. How do ADA and FMLA and other benefits work when the employee is living in another country? These are all questions that are a burden on a company. Why should they legally have to shoulder the burden?

Having fully remote employees within the US is a large burden in and of itself. It is very very hard unless a company has resources that can address that. Each employee in a different state or location is basically treated like a separate office. You are basically asking a company to open an office in Mexico.
