I was one of them... Its just part of learning. The pain makes it real. As for shitcoins *_on_* bitcoin, it still could have uses. What are stocks? Shitcoins... How could stocks cease being shitcoins? If their supply were finite. But there can only be one bitcoin. Its either the one hardest asset, or it will be replaced by a harder one, and all shitcoins go to zero, which, in other words, is the same as the best money eats all other money. But there will still be corporations, represented by shares of ownership. This is a hypothetical, but I think there's enough potential to seriously think about it. Bitcoin could fix the rigged stock market. Bitcoin could also fix democracy. But I don't think it can do things like this without data storage. So, the question returns to how we can making pruned nodes more useful.
