Yeah it's no accident SpaceX built their test launch facility on the beach in Texas, less than 10 miles from the southernmost point in Texas. Brownsville is about 20 miles away and is a natural, true deepwater port which is also helpful, but primary reason was to get as close to the equator as possible while still being on the US mainland. You can throw about 9% more mass into orbit on the equator than from NYC. Florida coastal property is mostly built out and southern Texas is mostly vacant + has a very favorable business climate and lax (state-level) environmental regulations which doesn't hurt either.
