There was a system for the witch trials as well; the accusations were just the starting point for the sham trials, torture, and executions. Are you okay with that because it was a system, even if imperfect?
Our justice system doesn't fail 1 in a 1000 times, particularly when talking about sex crimes. It fails far more frequently than that, given the prevalence of sexual assault and the rarity of convictions [1]. Additionally, there's an aspect that justice must be seen to be done: high profile repeat offenders walking free damages confidence in the system out of proportion to their frequency.
As above, if you want people to use a system, the system has to work.

What makes you think I'm okay with the current system? Upthread I even said "if you are unhappy with the way things are, petition to change them instead of mobbing".
Just because I hold the opinion that evidence matters does not mean that I am a bad person.
I haven't said I think you're a bad person; it's bold to accuse someone of a misreading based on your own misreading.
People aren't required to only critique a system using the tools that system provides; progress is often made when people step outside of the system (e.g. Rosa Parks) rather than quietly accepting it. There's evidence for that in countless civil rights campaigns.
