Did you read what I said? You talked about "force" and "mechanics" to prevent lawbreaking. If you can upload copyrighted music, it wasn't prevented? Nobody was "forced" not to break the law, they were able to do so but a remedy was implemented. Music is the lowest hanging fruit to enforce because you can stick the 100 most popular songs in a database and checking audio layer far easier, especially now, then anything else. But copyright music isn't the be all and end all of copyright violations, hence why the DMCA system exists. Does the person who uploaded
this have the rights to it? Because you argued that as Yuzu cannot enforce 100% law abiding behaviour it needs to go, and this is evidence of Youtube not "forcing" law abiding behaviour, so Youtube must also go.
The point is the standards you're holding Yuzu to are broken be many, many other companies and services, so they are evidently not good standards.
