the whole idea of "intrinsic value" is that it is not tied to "needs and wants", because "needs and wants" is just another way of saying "market" and on a market there is only speculative value.

"intrinsic value" as a concept is used to derive valuation of a company based on it's assets, liabilities, etc - fundamentals, as opposed to market capitalization. taking the concept of intrinsic value out this context is meaningless because nothing in the universe has intrinsic value.

You are saying that there are no infinite buyers and sellers, you are right but there are no infinite bitcoins too.

You are taking an example of beef cause you thing it has intrinsic value but let me tell you that in some states in India if they find you eating beef, they will even punish you for that.

Everything's value is relative based on the usage, and usage creates demand.

As conclusion, if community of libertarian will grow, Bitcoin's value will rise because demand will rise, if not, it is likely to fail.

But nothing is black and white, people will take sides and we will always have haters and lovers. There will always be enough bitcoin to serve people they want to use and not enough for the value to become zero.
