Countries don't 'need' borders because country borders already exist.
The issue is how countries and their allies decide how to control and manage their borders.
A country is broken if it cannot control its borders.
Well, no country CAN control its borders. If it's a vast country like USA, its borders with Mexico and Canada are so huge they will always leak.
A not-huge island like Britain or Ireland has a huge coastline, most of it unoccupied and unobserved , where boats can land.
In Africa, Europe etc every country borders many others and anyone on two feet can walk across borders at night unseen.
None of this is new, humans have been migrating for ever.
Most if not all EU countries, the UK, US etc try to control their borders but it's impossible to have 100% control. Humans will migrate for ever, they have done so for 1,000+ years- tand it will continue.
The UK has systems in place to try and manage and control its borders and the current government has brought immigration figures down.
Many things contribute to sustaining a country and making sure it doesn't become broken over and above its system in place to manage and control is borders. If the UK has zero immigrants over the next 10 years but internally other things deteriorate- the UK will become broken. It's the sum of all the parts that make up a none broken country.
The UK is not a broken war torn country and neither do we have famine. We still have basic security, a welfare system and rules of law. We have an equal society where women have the same rights as men. UK residents have free access to state education and health services at the point of need and other public services. The UK economy, infrastructure and social fabric has not collapsed. However there have been social fabric tensions and pockets of civil unrest. Hopefully such tensions and civil unrest and the undermining of the rule of law, education, welfare and health systems and government corruption won't escalate in the way we have witnessed in the US over the past year or more under the Trump populist president. Trump is pouring $billions into ICE in an effort to control US borders- but he will not achieve 100% control. The resultant price the US has paid with large scale ant ICE civil unrest and ICE murders yet to be determined and judged- by the next presidential election. Meanwhile the rule of law, education, judiciary, health access etc continue to be undermined and Trump's political corruption continues.
The UK has a democratic political system and the majority of the electorate decides which party, with which manifesto on all the above important issues secures the majority vote. The UK does have pockets of political corruption and civil unrest- but thankfully not to the extent of the US. The UK also has systems in place to identify, scrutinise, investigate and hold to account corrupt politicians.
