I'm an advocate of VPN but this is not the situation to recommend them but to chastise regulators and lawmakers for even allowing this. This is eroding our freedom of speech. I can see politicians expanding this and censoring terrorist speech and speech of certain political ideologies. It is the erosion our civil liberties we need to worry about.
If you want to start talking to lawmakers about wanting to watch porn without having to show ID, you would be dismissed if you're going to cite free speech being the right it is infringing upon. Privacy would be a better starting point, for example.
Big shame people are unaware of a century’s worth of obscenity law… how in western democracy the high courts literally found that laws like these violated free speech protections over “local prurient interests” and hence struck down those laws.
