As I said, there is no escaping market mechanisms, as value is market contextual. Certainly, there are assets with more or less stable value, but that is still due to the whims of what people (ie. the "public") are willing to pay.
Yes, the point here is not about the total valuation of each asset, which affects every holder equally, but about how individuals can influence, or not, the relative distribution of said asset.
If I'm, say, from a persecuted cultural group, I'll want to keep my wealth in an asset that has the same value whether I or someone else own it. Precious metals fit this bill better than both fiat and public-ledger cryptocurrencies.
