Again, people are going to have a hard time reading this as a morally neutral statement, but the fact that taxes exist depress the value of assets on the market. It's already priced in to the value of the asset, so it doesn't look like something that is "occurring", but it's still there. This is a morally neutral statement, and yes, taxes can fund things of value that can bring wealth to the society at large, etc etc, but all of that adds to the truth, it does not somehow "undo" this fact.

Isn't the net effect what people are interested in? If you impose taxes and then do nothing useful with the money, sure, that's an easy negative. And if you tax only unproductive private-sector assets and use them for public goods, that's an easy positive. The real-world situation is that you typically tax assets or income that are at least partly productive, and use them to produce things that are at least partly valuable. You come out ahead if the things you do with the tax money are better than what would've happened absent taxation, for some value of better.

The contention of people who support high taxation (as most of us in Denmark do) is that the net value is positive, and we are therefore overall better off and more prosperous than we'd be if we did not have taxation, or had much lower taxation. Partly this is because of a view that certain systemic problems can be much more efficiently solved by the public sector: it's difficult to imagine the private sector producing Copenhagen's public transit system, or the Danish healthcare system, especially for the same money. And partly it's because the prosperity we enjoy seems to generally require a backdrop of "things working well" that the state partly provides: good transit, low crime, few homeless people, safe buildings, functioning court system, educated populace, etc.

The industrial revolution was bankrolled by extreme government spending at draconian (compared to present) tax rates during the World Wars. Every technological and scientific breakthrough of the last hundred years was bankrolled by the state either directly or indirectly. This fact is lost on a generation that takes all of this for granted, because they naively believe that progress is the natural state of civilization.

Today, a president like Eisenhower would be called a hopeless bleeding heart liberal. Who cares that the USA became a dominant scientific, technological and economic powerhouse under administrations like his?

History is the best teacher. Personally, I will watch the disintegration of these naive "meritocratic" policies with great interest in the coming years. Who needs public investment in infrastructure, science or healthcare?

as a guy who's modeled and built economies for mmos, i can confidently say the more movement and activity in your economy, the healthier your economy is. consistent, steady growth and activity, rather than spikes (unbridled liquidity events) and valleys (accumulation stagnation), is the most desirable mode.

for a real world microcosm view, just look at the last six months of bitcoin activity. who on earth would consider that healthy?

There seems to be no quick way to liquidate that much wealth without destroying some in the process.

That's not actually wealth that exists being destroyed, that's a poor measure of the wealth represented by a stockpile being revealed to be poor. The quoted market price of a unit (which is basically the marginal price of the last/next unit sold) times units held is not an accurate measure of the total value (wealth) represented by a stockpile of a marketable asset.
