This is the important point. You need the right to not be discriminated when you withhold your consent, otherwise your consent is effectively meaningless, as it is forced on you by your impossible bargaining position. This is one of the central pillars of the GDPR without which it wouldn't work at all. Be advised to make asking customers for consent that doesn't directly benefit them illegal as well, lest you risk creating another wave of malicious cookie banners.

Which is why "we don't serve patrons without shoes and pants" policy is unconstitutional, yeah.
If you don't want to agree to a business's demands — you're welcome to not deal with them and look for an alternative. All the alternatives have the same (or even worse) demands? Unless you can prove collusion, that's just how the invisible hand of the market worked its magic out. Go petition you congressman to violate laissez-faire even more than it already is, I guess.
