Value is a product of demand for both USD and BTC. So as I said above, your question was tautologically true: if the demand of Bitcoin will always be high, then yes it will be a store of value, because things that are in high demand have value. But that is true for any good. I could ask the same question about cow dung, or any scarce good. If the demand for cow dung was as high as the USD, will it be a stable store of value? Yes.
