>Money doesn't really have physical value, only speculative (you want it because you trust that someone else will want it in the future).
And because you need it to pay your taxes in it
>Shares in public companies don't really have physical value unless you own enough to change the management. Sure you 'own' that fraction of the company and their assets, but the managers of the company don't ever have to pay you out any of it. Almost all the value of a share for most people is in its speculative value.
Nowadays the price depends mainly on that yes, but dividends are a thing, and legally (which is the only thing that matters in finance anyway since private property is also only legally a thing) you own that slice of the company and its assets. The price and the value are different
>Art generally doesn't really have physical value, the value is almost entirely in the story that goes with any specific piece. This isn't just true of modern art, being part of the story of the Mona Lisa is much more important than the aesthetic experience of looking at it (they let plebs do that for free!).
And in the tax avoidance schemes it enables
>Education certainly isn't something with physical value. Sometimes it has utility value for what you can do with it, but more often it's just something that people want you to have because it distinguishes you from people who don't have it.
Now we are getting more interesting, what's the difference between physical value and utility value? What's the difference between social value (it will make me desireable) or personal value (it will make me happy) and "physical" value?
>Insurance doesn't have physical value, it's more the value of feeling safe, which is a meme.
Only if you don't understand probabilities and risk management. Also, good luck buying a house without life insurance
Things have value because we need them (inelastic part of the supply-demand curve), things have a price because we want them (elastic part of the supply-demand curve).
