I
almost like your fentanyl comparison -- but where it fails to me is that your biochemists will have very specific ideas about what will happen.
To me, tech's war on crypto feels more like "the War on Drugs." It's fine to be against, but it's the extreme lack of interest in discussing detail (which if you were anti you'd need to get into to stop it) and they don't do that.
Let's say you wanted to attack crypto on principle? Great. First you'd need to ID and figure out their weak points. Bitcoin kills the environment so you attack there. Now, others don't - but a lot of the post ETH coins are centralized with a small number of founders, so you can get them there. Now, ETH is going to be harder because they've done a better job on decentralization...
ETC.
That little paragraph above is orders of magnitude more detailed than any actual attack I've seen. Which again- SUPER WEIRD for tech folks!
