The company needs to account for which state(s) my income taxes are to be paid towards if I'm w2'ing their situation, as a citizen of the United States, I give as little information as possible because then I'm not able to be 'wrong' or somehow incorrect.
This leaves me with exactly two addresses for location, one for shipping things and one for "The state in which you reside". Residence is a legal thing, you can travel and be nomadic while maintaining your resident status within one or more particular states.
I've been working remotely for 10+ years like the parent comment, and it would make a very interesting impact on my tax history if what you both are saying holds any water.
