Again, though, it takes time to generate evidence of voter fraud and conspiracy. The system doesn't allow the time to investigate it. I don't know what to tell you if you don't see that this is a problem.
A massive voter fraud conspiracy would be a years-long investigation. There will never be a real-time remedy for something like that. You build a system, make rules, and then live with the results that system produces.
So when Trump associates ask a court for relief at the level of tossing 100's of thousands of ballots, decertifying the result, or just declaring Trump the winner - it shows they aren't serious about this. The goal is not to secure democracy against election fraud - the goal is to protect Trump's fragile ego, providing he and the base a rationale not to be what Trump despises most - a loser.
