Any "legally-binding, two-party transaction" between an individual and a large corporate conglomerate is a lost battle (or more precisely, a not-even-fought battle) for the vast majority of individuals.
80% of buyers of anything simply smash "Accept" (and watch through ads/spam) until their device shows the content they wanted to access. (Statistic is made up, but I think it's hard to refute.)
Do you call that "explicit consent"?
