Wow, quite a post. This is a serious question which deserves serious answers and not this post. Your forgetting where the backspace button is is the least of it. No need for the vitriol. There are good people on this board, treat them with respect.
That said, I don’t see this as being all that much of a problem. Schools which are academically selective are going to look at the applicant’s high school and see what kind of history they have with that school. And (Herb’s daughter’s school notwithstanding) most colleges still use mathematics placement tests. It’s not going to be ideal (underrepresented groups are going to be disproportionally negatively affected, sadly), but the schools and students will adjust. The instructors will be prepared for these things; it won’t be business as usual. It’ll work out. We’ve got bigger problems.
