I don't mean 'current' as in 'currently living overseas'.
I mean they've gone, fairly recently, through the process of finding work and obtaining a visa. People who've emigrated ages ago will have had a completely different experience. You did mention that your friends had been working happily out of the EU for years.
If you're going to say all your happily settled friends did emigrate quite recently, then they're probably not all that settled, in legal terms. I know you're steadfastly ignoring all the small technicalities like having no permanent right to work or stay in your new country, and fewer benefits or securities than its citizens, but in every country your rights and entitlements are limited until you become a citizen. This isn't a big deal if you're young and transient, but it's a huge issue when you have a family, or property, or a business.
Australia, New Zealand, America and Canada all require multiple years of legal residency before you can even apply to be a citizen; around six, on average. Some of them require that residency must be as a permanent resident (ie greencard-holder or equivalent), which is often a status you can only gain after a specified amount of time working on a limited-term visa; it may take several years of this before you can bump up to permanent resident, and then start the citizenship clock.
So it takes a long time and a lot of effort to become a citizen. Until you are a citizen, you can't truly call this country your home. Obviously, it may feel like home, and you may have raised a family or bought a house or contributed lots, but on a purely legal basis you're not quite fixed.
Either your happily-settled friends emigrated years ago, long enough for them to them to have eventually gained citizenship, or they're only allowed to stay in their new country for as long as their visas state or they comply with the terms of their permanent residency.
But you're not interested in the details. You've repeatedly ignored all attempts to show the difference between moving/working somewhere as a right, and moving/working somewhere on application: the additional money, time and obstacles. You're more interested in trivialising everyone's concerns: doom-sayers, bee in your bonnet, need to get out more.
