Edit: Don't get me wrong. If the reported profit margins at Verisign are correct they are clearly continuing to exploit their privileged market position unreasonably
It's also my understanding that the trademark rule only applies if the trademark was made before the scalper purchased the domain name. If you're a startup or just someone who wants the domain then you're out of luck. Your only options are to pay the asking price or hopefully wait until their claim on it lapses and they don't renew.
If you want to address squatting, then address squatting. If you want to address people squatting on new domains (as if there are many squat-able .com's left), then change the registration for new domain registrations only (and not renewals).
A change like this will primarily affect small domain holders in a way that is financially not worth fighting back against individually. I don't really see a "devils advocate" position here.
That said. I think the small renewals are the part that makes holding onto these domains for years possible...
Random example. 20 years ago I had a one person local IT consulting side-gig. The domain was a not very useful, active less than a year and grabbed by a speculator as expected when I let it expire. It's been parked many places for years by various folks, current parking pages quote says they might be able get it for me for $120 [1] -- I could care less but if someone with less tech experience wanted it for their new small business they would likely bite.
Is there a economic mechanism you recommend to prevent this sort of thing?
