I'm sure it would reduce ransomware attacks by an order of magnitude. These are not simple attacks and the cost to launch them isn't that low. It requires large effort from groups of smart people to penetrate these corporate networks and it's time-consuming for attackers. The opportunity cost for these smart people is high, most of them can get a high paying job. The reason these attacks persist is because it's so lucrative. These's definitely a break even point for attackers. If 80% of ransom payments are stopped the attacks will stop because it will no longer be profitable for attackers.
