Starports, Mains, and Big Time Shipping (TM)

... The mega-engineering feats required for a beanstalk are simply not needed.

Yea - the toll fees would have to be pretty steep... though one shouldn't discount the 'status symbol' aspect (i.e. like the plethora of skyscrapers in RW cities supporting egos as much as manpower). And for lower grav worlds (esp. with little atmo and no other nearby graviational bodies), this would be more feasible (but still probably require an exceptional justification without nano-tech).

Note: MGT Core pg.4 does mention 'Grav-supported structures reach to the heavens...' at TL-11 (Pre-Stellar).

MGT Core isn't just the OTU, though. It addresses some SF tropes from other sources. Doesn't mean you can't have them in your game, though.

The OTU does have references to grav cities, but even those are peanuts to a Beanstalk.
