Nope, the problem is that disputes can be (and routinely are, by default) rejected by the claimants with no risks to them, again. Escalating beyond that risks a copyright strike (three of which mean your channel is gone, but even a single strike costs you access to various features).
The best approach is to only escalate if you understand the specific legal situation of your video and can make a case that would likely hold up in court. Needless to say most creators aren't well-versed in legalese and the risks to the creator are much greater than the risks to the claimant so most creators avoid this for "less important" videos.

Doesn't quite solve the spam problem, but seems like a step in the right direction.
