Appeals to the founders are not compelling to me, they intended to have tons and tons of private activity regulated in the purview of private enterprise.

I agree that perspective might have been misplaced, but the founders were not in favor of powerful oligopolies under the control of the government.

Valorization aside, let's remember that the US has only been close to a majoritarian democracy for the last ~70 years or so. We can't necessarily look at the intentions from 200 years ago to decide on how political structures should be made, but we can observe their successes and failures.
