>how can they land this big ass blimp thing safely on earth? this looks impossible.
No, but seriously, the landing is the more sane part of this proposal.

There is still stress in the envelope, and for all intents and purposes it is still directly proportional to the amount of buoyancy/weight you are using. You can't just "get around it" by using the square-cube law, except at small scales where handling becomes a bigger issue than flight stresses (due to that factor sort of necessitating a constant bare-minimum envelope thickness).

That's a slightly different story, and it follows the scalability laws of rigid aircraft more than that of inflatable airships... but ultimately it still ends up showing almost benefit from the square-cube law. Additionally, they have much poorer payload-fractions than that of their soft inflatable counterparts.
