You'd have to dig a lot in order to experience any significant change, and it wouldn't really solve this for you. If you dug all the way to the core, the mass would be roughly evenly distributed around you, so you'd experience almost no gravity.

Digging does help with radiation shielding, though.

A space station has the problems of no durability, and effectively being stuck in a submarine for your entire life. There a huge host of psychological problems that comes from that, which would be hard to manage. Not to mention a space station is basically human only, and cannot be allowed to break down at all, ever.
Those are unfortunately also problems on planets. It's a question of if you prefer hard vacuum outside or abrasive dust.
