It isn't clear how much immediate day-to-day difference this would make to SpaceX. Company leadership moved to Texas some time ago. Production of Starlink user terminals was already moving to Austin/Bastrop (with component production possibly migrating to other countries) and Hawthorne Raptor production was likely being migrated back to Boca. Hawthorne mostly hosted development support for legacy products like Falcon and Dragon with the expectation that these offices would close when these products are no longer being offered. Starship software development will probably eventually be migrated to Boca and other projects will likely follow.
It probably makes sense for the business to move to a venue with a more favorable regulatory environment. The company has been party to multiple lawsuits related to sexual harassment, assault and workplace injury/death and the ability to try cases in a more friendly environment will make it easier to encourage employees to optimize productivity.
