I have a feeling this is a nuclear option.
If this is implemented, then pro-copyright extremists will argue that running or using a proxy is prima facae evidence of criminality and then lobby hard to make it illegal. Result? Anybody with a legitimate (or illegal but ethically necessary) reason to use a proxy will lose out.
The OPs' hope that the pro-copyright extremists won't fight back hard, with legislation to ban proxies, or force China-style "real ID" laws on Internet users, is naive at best, and ultimately, dangerous.
