The power to prosecute and the actual ability to prosecute are two different things. They currently can't prosecute CSAM offences nor piracy due to capacity. It won't happen.
The problem is not with the state actually prosrcuting all, or even many vpn "offences". The problem is that the legislation gives states another powerful tool to prosecute people they find annoying but cannot easily punish for clearly breaking other laws.
Well true but wait until you do something else and they pile that on top of it.
I think VPN prosecution could happen if it was treated more like traffic offenses than like felonies.
Force ISPs to log all connections and make ISP customers accountable for their traffic, like they are in Germany for example. If you detect an IP to be used for a VPN, ask every ISP to disclose al customers who interacted with it and issue them a ticket. Three tickets and you're denied internet service for two years.
I think this would scare most people off.
