This is absolutely true. Most people care about price over any other variable.
Yet even areas where there are people who prioritize security consistently fail (Apple vs Jailbreakers, Open Source SSL/TLS developers vs CA validation failure). There is literally no code on this planet you can trust 100%. Even the code that sent people into space had bugs.
edit: I do like the idea of cryptocurrencies, but I don't trust software enough yet. I'm more bullish on the idea of P2P shared blockchains in the form of namecoin as a replacement for DNS etc.
