I'm pretty sure I could incorporate a business virtually anywhere I liked (within reason - there are obvious exceptions). No one is going to throw me in prison if I try to start a company in Singapore, or Chile, or Hong Kong, or any other whatever. You don't have to physically MOVE there in most cases...and even if you did...what's stopping you? And as to Visa issues...there's ways to gain residency in most countries...you can make it happen if you want.
