There's opportunity costs for engaging in ransomware rather than doing other activities. If you're good enough with computers to do ransomware, you're also probably good enough with computers to do legitimate work. We don't need to completely starve out the ransomware actors, we just need to make it less lucrative than their other alternatives. There's still a problem - nothing's stopping India, Australia, and Ireland in your example from benefitting from the reduction in ransomware without paying the costs for disincentivizing it. Free riders are a problem for public goods, such as low-crime environments.
