So I’m required to develop a bad version of my product for the small subset who don’t consent?
Sounds a ton like the Windows Reduced Edition fiasco all over again but at a much more massive scale - forcing by law the development of a product almost no one wants.
You don't need consent for the cases when processing personal data is necessary to provide a feature for the user. For example, if you have a "find my friends near me" feature, you don't have to ask for consent to use the user's location for that purpose.
So there's never a reason why the product must be worse for any particular subset of users.
When you need to ask consent is when you're trying to use personal data in ways that aren't directly related to providing features for that user. Like, for example, ads.
And you can't develop a bad version to "punish" users who don't consent to those unrelated uses of their personal data, because then the consent wouldn't be freely given.
