Because what you’re asking for is untenable in a world of billions of people scattered across countless nations, at least without cutting off the internet outside your borders entirely like North Korea. And trying to force the issue domestically just results in oppression and restriction of human rights. The global digital world is a formless, borderless space; this “freedom VPN” thing, Tor, I2P, v2ray, satellite internet, etc, you will simply never be able to fill all the gaps. Those who want to will get around it.
Even China, who has probably the most sophisticated information controls in the world, can’t prevent leaks through the Great Firewall. They just rely on it being “good enough” to restrain the general public.
Put another way, your country can make all the laws it wants, but it can’t change the laws of another country or force them to change how their network behaves, at least not without a fight. And in a world of billions of people, the global network will always be doing something that you don’t approve of, somewhere!
