People will always misuse good meant inventions for bad things. It's something we have to accept as part of the game of life in general.
Not really, if countries can restrict access to such websites maybe that will reduce the gambling to at least some number but I know most of the people who are into gambling and crypto will already know about VPNs and other stuff so it's almost impossible to stop such things like you rightly mentioned, part of the life.
That last paragraph was more headed towards the fact, that you can't stop selling knives for example, just because people misuse them for murdering other people. There is a lot of things that are misused for bad purposes and not for the usecase it was intended to. Even cars are used as weapons nowadays sadly. This is also the point Kim Dotcom used to defend Megaupload and I think he is right in arguing like that. He just provided a platform, where users could easily exchange big amounts of data, that couldn't be sent via email for example. People then misused his platform to share all kind of copyright stuff like music, videos, whatever. I don't think he was sad about it, because it brought him shitloads of money, but it (probably
) wasn't his intention.
So just because crypto is used for illegal gambling activities, doesn't make crypto a bad thing per se. Restricting access to certain websites is never a good thing imo, you are just opening Pandoras box with it, because where is the boundary ?!
