Not sure if representative for "bitcoin enthusiasts", but here is how I see it:
As the written word spread in Europe after BC, it layed an important cornerstone for democracy and changed the world for good. Noone would argue with that, right?
Ok, so let's look at Europe from 500BC-1300BC. Corrupt monks forging official documents, under some goverments up only about 60-80% of the were real. Monks were people of god, so noone really investigated. For a long time, the emperor would sign with a simple line, because he couldn't actually write. Wow, how is that more valuable than spoken word?! Where is your democracy? Women can't read, poor can't read. Knowledge is stored exclusively by the church. Turns out writing things down is actually a really backward philosophy! Or is it?
And that's where we're with Crypto right now, IMO. I'm not saying this is as revolutionary as writing, not even close. I'm not even saying it will turn into a good thing. BUT I really like the underlying idea, the concept, of it. Of course there are greedy shitheads, companys taking advantage, fraud and projects which are uterly useless. But yet I didn't came across an argument which convinced that the concept of non-centralizing via blockchain can't work.
So, to actually answer your question, I think we shouldn't mix up the discussion about the philosophy, potential and future of Blockchain with individual cases like "is this pump and dump worse than 2008 greed of banks" (which is also an important discussion, but a seperate one).
Does that make any sense?
