Imagine a government so hypocritical that it requires it’s citizens to prove they have health insurance, but not that they prove they are citizens.
Now compound that idiocy by implementing a policy that says if you refuse, are unable to, or are actually not a citizen then you will receive free health insurance paid for by those who are citizens and are forced to by the insurance because they are citizens.
The only way you could dream up such a ridiculous policy is if you actually wanted to slap citizens around and overwhelm the system.
