Have you actually done any of the 7 options you mention? (If you have, I'd love to hear details). I think you may be going on bad information on at least some of them. For the record, I have a federal conviction in the US. I got out of prison at age 28, finished my degrees (CS & math), and succeeded as an early employee at a startup, so it is possible. Then in 2014 I went to Argentina for the supposed "2 year citizenship", which ended up taking 6 years, and a good amount of money to pursue it. I lived on money generated entirely in the US - the economy of Argentina is much, much worse than the US. If you're basing your research on the baexpats forum and specifically bajo_cero2's comments, that may have been true before 2013, but not anymore.
I'm not saying your suggestions are 100% impossible, but they're more for people who are on the run (i.e. very desperate) rather than those with a conviction.
There’s also the Dutch-American Friendship Treaty which allows you to open a business and live in the Netherlands if your background is clean for the last 10 years. You only need a €4500 investment in the business and another couple k for the application fees. This is what I did.
