Still the same fallacy. We could put up the same CCTV cameras and get at least as good an outcome if the problem weren't as bad to begin with.
Firstly, the cost to each player is extremely small - so their incentive to "do something about it" is small. If a person receives only one email a year nothing will be done.
But if he receives his life's spam in a year he will do something about it.
Also note that most countries will not change their laws for a "small" problem. But if a problem is perceived to be large enough the law will be changed.
