<- Democracy is vulnerable to a 51% attack.
If you are referencing that to be directed towards America though it doesn't apply as the U.S.A. is a republic. Just thought you should know that. While the voting structure is certainly different, example of president can't win 51% to 49% for the electoral college and other various things. Although bills and voting for laws can certainly be won by 51% to 49% in the senate, it is not true in other areas.
It's still a 51% attack, it just changes what you need 51% of. To control the Presidency, you need 51% of the electoral college. To control the law, you need 51% of the Supreme Court. For most things, you just need 51% of the population.
Further, in a republic the very tiniest voice has a chance to be heard. Democracy(which bitcoin is) eliminates the tiniest voice and gives it to the majority(big miners).
So you kind of completely contradict yourself by having that as a quote if you believe in bitcoin but not democracy...
That's not quite what I'm trying to say with that quote. What I'm trying to say is that in almost every imaginable system there's a majority of something that can hurt you if it wants to. With Democracy, it's usually the population, but sometimes other things. With Bitcoin, it's the mining power.
The more subtle point is that there are not, and will never be "trustless" systems. There will always be a majority of something that can screw you if it colludes against you. The important thing is to understand precisely what it is that you are trusting, how much damage it can do to you, what its incentives are to betray you, and what you can do if it happens or is in danger of happening.
Try not to be a pseudo intellectual in the future!
I'll do my best.
