This 100%, well put.

Within businesses, people have evolved far past market definitions where widget x¹ competes with widget x². Our political savvy as consumers would improve if we could see that as well.

For example, why would Google approve a product like Stadia? What does it compete with? Nintendo, yes but not really, since so many Stadia players have a Switch also... just like most of us have Facebook and Twitter accounts. But maybe they're true competition is Netflix? Social media? Users are giving Google their time = data = insights = further monopolistic advertising power.
