But what about the people that don’t use ChatGPT or they use Grammarly and the algorithm says they have a 70% match, then what? Make them redo the assignment? How is that fair?

Then what I gave you as a prompt, would reduce the detection from the algorithm to 0% so your point is flawed in the fact most of these detect ChatGPT software/sites are open to the public rather than a proprietary one only academia has access to.

Per openai ceo, humans adapted to using calculators in class, this will be true with ChatGPT.
