You're trying to push the idea that because someone can hide a piece of gold under their bed, that means obscured blockchains can have "value".

That reminds me of my 6 year old daughter who thought because she had 6 coins in her piggy bank she could buy a house.

Unbacked monetary media take a very long time to garner individual trust, then public trust, then public consensus, then public endorsement. Only after that "right of passage" phase comes value anything like the status of gold.

The only reason gold gained any value in the first place was because it got kicked about in the open for thousands of years and was found to posses true monetary properties (which are very rare). But it was public consensus that ultimately endorsed its value. That led to hoarding.

But Gold never had any obscurity of its own. If it had done it would never had got past the value of sand.
