a) Bitcoin as a solution is dis-similar to pretty much all other modern solutions. It is not inflationary on a theoretical level and thus does not require that an economy grows exponentially in order for the economy to perpetuate itself. So, a lot of the standard economic theories about capital do not necessarily apply in the same way.
Well, I think you would agree that it has to grow to a degree, or at least it would be good if that happens. For instance, I think SR is contributing a lot to the long term viability of the currency as a store of value (the aspect of Bitcoin I think you are mostly interested in). Even if it's only for a time, it helps bootstrap confidence until a critical limit is reached.
People getting constantly ripped of in the vastly underdeveloped and (imo) malformed and downright ugly economy which currently exists is not at all helpful.
What I meant is, the path to formation comprises malformation. I'm as sorry as you that things developed this way, and it would be much much better if they didn't, but I think all this is part of the thinking process. It's hard to predict the future. As a result of all this, I'm confident that we will have more and more functional ways to do business freely and it will be an overall win. However hard we try, we won't be able to come up with a working thing without going through these phases.
I lost coins in a wide variety of transactions. Hell, even bitvapes.com has failed to deliver my items. It's an ethical dilemma. On one hand, you could be giving money to an unethical person, thereby incentivizing unethical behaviour. On the other hand, I think you have the duty to give a chance to people who try.
I would have ten times the coins I have now if I had just hoarded. Maybe this is just me refusing to believe I made a mistake.
Here's why you are wrong: The whole economy can run off 1 Bitcoin. That 1 Bitcoin or more can be invested and used as much as you like. The persons holding more are holding back nobody.
I'm not saying they are. By all means, Bitcoin has the capability of being a store of value. I'm just arguing against the contrary, that investing your coins in risky enterprises are pointless, stupid or whatever.
