Hell, you could build a >1g torchship using nothing but the ocean.

Alternate ending to Half Life Alyx where it turns out the scary thing the Combine has locked up in the vault is Chell.

There's also the gravity interaction: an infinitely falling object that never reaches the bigger body is also accelerating the bigger body.

Your forever falling object is shoving the earth upward, very slowly. That could matter in the long enough term... But it seems kinda meaningless compared to the other ways you could use a portal.

Still, might be handy if you need to adjust the orbit of a planet and are willing to wait.

It would be a very Cave Johnson thing to try to fix global warming by pushing the earth away from the sun.
