I actually think the onus is on you to explain why Bitcoin is devoid of value. Going on tangents about "what empirically works" isn't an explanation even worth reading. It's like saying: "well the system hasn't collapsed yet so might as well hold on to your dollars and bury them in the yard".
I'll take a stab at that one.
Bitcoin is not devoid of value, or else there would be no price. So bitcoin has value. For now.
Things have value because of three things: permanence, utility, and scarcity.
A bag of rice, or a bar of gold, have intrnsic value because of tangible permanence and utility. The former isn't worth as much because it isn't scarce, while the latter is.
Fiat's tangible permanence it is the stability and structure of the government and the utility is the productivity of its citizens i.e. your ability to buy goods in that country using those dollars. The US dollar has more permanence and less volatility than the Venezuelan Bolívar because the government is more stable and you can buy more with it. So even though there are less Venezuelan Bolívars than US dollars, the US dollar has more value.
Bitcoin is very different. Bitcoin is backed by decentralized miners, which are impermanent. Miners need to create coins and immediately sell them for fiat in order to pay the power bill. If the price of bitcoin drops below the profitability threshold, the miners go bankrupt and the entire system backing bitcoin dies, along with bitcoin. Ironically, the stability of miners backing bitcoin infrastructure is tied to the stability of the bitcoin price, yet selling pressure is intrinsic to the system, so it's a snake eating its own tail.
Unlike humans that create value through work, Bitcoin destroys value through Proof of Work. So, it actually has negative utility baked into its own existence. The entire system only works with a constant influx of new fiat. No fiat buyers = total collapse of the system as a medium of exchange, as exchanges can no longer happen.
But does Bitcoin's extrinsic utility as a medium of exchange or store of value supersede the negative utility of Proof of Work?. You could make that argument. But that is not intrinsic to bitcoin. My pet rock can function as a store of value or medium of exchange if I have willing buyers. And you could argue that my pet rock is superior as a store of value because I don't have to constantly whittle it away through Proof of Rock.
Whatever utility there is in Bitcoin comes from the global network of willing buyers that facilitates easy conversion between Bitcoin and fiat. All good, except that we've already shown that the system is impermanent and, without buyers injecting new fiat into the system, the miners will deplete the battery to zero. So, if Bitcoin's utility is wholly predicated on fiat conversion, then what does it bring to the table? Fiat already exists as a store of value and medium of exchange. Bitcoin is just a layer of inconvenience on top of that. It's a nop.
Unless, of course, you perceive the value of Bitcoin to be an easier way to transfer value between jurisdictions outside the law. But that won't last. Bitcoin will either be declared illegal or regulated. So whatever utility there is today will vanish.
So no permanence and no long term utility. That leaves only scarcity as the value. Bitcoin is scarce, but can be fragmented infinitely, so it isn't really scarce.
So without permanence, utility, or scarcity, the value that exists to today is only transitory.
