Because people don't know about it.

Also, for many people, even doing something like "sending an email to counter claim" is too much work for them to bother doing it.

You'd be surprised how many people won't follow through on something when there is even the smallest barrier to them doing so.

Things can get to be pretty technical, when people are talking about the minutia of a counter claim to DMCA. It does not surprise me that info like this is not well known.

But we are not talking about the DMCA system. We are talking about YouTube's own system that is not DMCA and for which they are not required to provide due process.

So, what is this magical Google email address? I don't think it exists.

I am glad that you asked.

It is provided on the official copyright.gov website.

All this stuff is in a searchable database that is helpful provided by the US government, and is required by law.

Ex for Google:

https://dmca.copyright.gov/osp/publish/history.html?search=G...

For DMCA, it's [email protected]

But it's more likely that you get a Youtube takedown, which is not related to DMCA. There's a UI for that in the mgmt. console.
