Immigration laws aren't very good in almost all countries. Governments do want to plan better and have good-sense policies that let in people who can integrate and contribute. But they are held back by a basic human instinct: xenophobia. The average person is OK with seeing one stranger in town, but start feeling creeped out when they see handfuls, and get downright paranoid when exposed to large numbers of foreigners. Inevitably, this instinct becomes a tool for a subset of politicians, who then play power games with immigration policies. I'm not sure exactly why, but there are also some systemic habits that make immigration much worse than it should be. For example, it's nearly universal that countries will put tight global restrictions in place because they want to reduce immigrants from a single place. E.g. looking at Central / South America right now, a lot are tightening up policies against all nationalities because they don't want immigrants from Venezuela. This is really baked in -- look at how intense the outcry was when the Trump administration put restrictions on specific, named countries at the beginning of the pandemic. That's generally just not done. So in short, you may be correct that there's a theoretical human right, but the world just isn't going to realign in that direction anytime soon. In the same way that it's sort of a human right to have pleasant, non-hostile interactions with other people, but that would also be impossible to effect; there are simply too many assholes in the mix. One thing I've often pondered is that there should be some sort of non-governmental group that you can join or qualify for, which evaluates and vouches for its members and guarantees their good conduct in any country they visit. Basically, the same thing a passport does. But it's a pipe dream in a world where almost everything is based on accidents of geography. As a side note, there is a new sort of route to immigrating for people in your situation, these days: instead of going to another country first, instead work remotely, build up cash, and use that to immigrate. (Because, as others have pointed out, money is one pathway to immigration.)
