Here's what I posted there:
This obsession with 'backing' demonstrates a gross failure to understand the subjective theory of value.
What backs gold??? Nothing other than the subjective valuations of individuals. The same is true of fiat currencies, except here individual subjective valuations concern matters such as 'not getting arrested' or 'not getting shot.'
Bitcoin is a technologic, cryptographically-rooted, informational commodity. It has unique, desirable properties inherent to its design and structure. Individuals subjectively value these properties. Their reasons and value scales differ, but the simple fact that people are already trading Bitcoins proves that it is subjectively valued.
You talk about 'confidence crises.' This is unique historically only to fiat currencies (and paper currencies built fractionally on commodities like gold). The subjective valuation of fiat currencies is derived from political considerations. As such, confidence in them is built on the ever-shifting sands of political perceptions.
When was the last confidence crisis in gold? There hasn't been one. People value gold for its physical properties defined by the laws of nature. Those properties do not change and individuals have continued to subjectively value them.
The same is true of Bitcoin. Its properties are rooted in our present understanding of cryptographic principles. As long as individuals continue to value properties such as anonymity, decentralization, finite supply, low transaction fees, ease of digital manipulation, ability to integrate smart contracts, etc... we have no reason to expect a 'confidence crisis.'
This will be true as long as the cryptographic logic buttressing the system remains sound – just like the laws of physics underlie the desired properties of gold. Breaking this cryptographic logic (akin to cheap transmutation of lead into gold) would require breakthrough advancements of our knowledge of cryptography and discoveries on hitherto unsolved mathematical problems. But even in this case, the open-source nature of Bitcoin allows it to evolve new cryptographic implementations that would avoid such problems.

People dont understand value and money.
