At this point we're overanalyzing everything to hilarious levels, even though the writers themselves didn't think any of this through. I'm gonna do it anyway:
Because in Hulks instance we were dealing with mystical cosmic mumbo-jumbo star-energies, which were focused on the Hulk and Hulk alone. Otherwise Hulk would have sunken into the ground and straight through the Earth, if the weight of of a star was resting on his shoulders. Especially because that would have also made Proximas strength levels rather questionable.

I think that theory could very well apply to Proximas speer and its star-weight-energy. And you don't see Mjolnir being pushed through the ground, because there are mystical aspects to all of it (as related to the video).
The Last Son is simply different. I could buy him not sinking through the ground due to him actually flying, while pretending to stand. But other than that there should be clearcut side-effects, which can't be excused with mystical mumbo-jumbo.
