What is the problem, exactly? What responsibility, exactly, does the state have to make mass migration viable? It seems like you’re making really big assumptions.
Make a list of the costs and benefits for both too lax and too strict borders for all the countries your ideas should apply to. Account for the costs and benefits of both incoming residents and outgoing residents, both from the point of view of the people moving, and from the point of view of the state. How would you balance lax borders against the downsides like weapons, drugs, human trafficking, and other criminal activity? Would you do anything to control the flow of too many people at once to places where there is no housing or utilities for them? Would you do anything to stabilize the economies of countries that lose or gain too many people in a short period of time? What do you propose for settling disputes about the border policy? If other people in your country don’t agree with your idea, how should the policy be decided? What would you say if you found out that the majority of people in the country you live in want strict borders, and vote for them?
The state has a responsibility to keep people happy. If states keep people sad, we should abolish them because they have no good purpose. Borders don't keep people happy.
Very telling that you didn’t address a single one of my questions…
Pls see Chesterton’s Fence. If you think borders serve no good purpose and that nobody is happy about them, it’s because you’re ignorant about borders and haven’t bothered to read anything or think about it at all. Lots of people want borders, and for better or worse, lots of people are happy about them, which is why they are there. You don’t get to take borders down until you understand and acknowledge the reasons they were put up.
Which state are we discussing? Can you point to a legal document or constitution for a country that defines the state’s purpose as keeping people happy? Maybe one exists, but I’ve never heard of that anywhere. I think in most countries, it’s your own responsibility to keep yourself happy. A lot of countries will, however, try to keep it’s citizens safe and try to protect the economy, and borders are seen as one of the tools to help meet those ends.
