Wayworn, the bottom line is that you don't understand U.S. law or the law of eminent domain. You give the example, which apparently shocks you, of an ex-pat in Spain being subject to eminent domain. In the United States, everybody is subject to eminent domain. I'm guessing that in Spain, as in any other country, that if a highway must be built, it must be built whether the property seized is from an ex-pat or from a Spanish citizen whose family has lived there for a thousand years. In other words, you are screaming how terrible it is that someone's land can be seized for eminent domain to build a new road, without any awareness that this is already the law, and pretty much always has been the law, in the United States. I know people, gosh, right here at home, who have had to sell their property (or what remains of it) for new roads, levees, developments, etc. If you think this only happens in the Spanish speaking countries, you need to get out more. Seriously.
You are the one who raised the issue about someone having a road built where they had a swimming pool on their property in Spain. That's why I quoted you directly, because I thought your comment so odd that I was afraid of being accused of taking it out of context if I didn't use your own words.
Now I'll admit it freely. I don't sit around going boo hoo because I had a swimming pool in a foreign country and there was a need for a road and my swimming pool wasn't considered sufficient cause to block an entire road for a community. I do know people who have had to sell their property to permit the expansion/improvements of the levees right here in Louisiana. Are they going boo hoo that they were ripped off? I think many of them wish their property had been purchased and the improvements done considerably sooner. Some 1,300-plus people would still be alive if they had.
I will freely admit that there were at least two con artists, the Brothers, in Costa Rica. How many con artists are working right now in Florida? In addition, Florida and much of the Southern U.S. has a huge violent crime problem that causes considerable problems for older people.
The hurricane/natural disaster risk is also pretty substantial this time of century in the U.S.
I don't see the need to pour cold water all over gypsytoes' plans -- especially when the objections offered just don't seem to be "serious." Wow, is there eminent domain in Panama (or is it Spain? you don't seem to be sure), well, so there is in the United States also. Are there con artists in Costa Rica? No kidding, well, so there are con artists here at home. If you're going to offer an objection to the move, let it be a serious objection. A con artist is not more terrible because he speaks Spanish.
"All kinds of things can and do go wrong" is not a serious objection. "All kinds of things can and do go wrong" to everyone who lives long enough, whether they travel or not. I wouldn't mind your negativity so much if you had a more serious example than your friends in Spain who had a road built where they had a swimming pool. Or worse, that it was friends of a friend who had this happen -- and maybe it didn't even happen at all?
