Yeah no. We already see various forms of direct government censorship and indirect censorship through private entities holding key social media platforms.

The last thing we need is a full embracement of shutting down and censoring. Also it is entirely impractical, as you have overlaps as two nations at odds with each other might both be on good terms with a third nation.

Finally, what happens when you go on holiday? Do you want special government approved agents to be the only ones eligble to purchase a plane ticket from and book a hotel with? Prepare to pay triple and end up with a system even more ripened with corruption than the current economy.

Finally it is naive to think that this would stop competing disinformation. Just have a satelite interface and maybe some private network as bridge and voilá.

All this does is fuck over the people more, while the elites get to continue their shit.
