A barrier to entry does not mean that entry is physically impossible. Barriers to entry are nothing more than artificial obstacles that make one option artificially less competitive in the market place than others
There is nothing artificial in the choice of money.
The people chose their money, not government.
Nice try at a weak non-sequitur, troll.
I talked about artificial obstacles as barriers to entry as it applies to "other" forms of currency, and you respond with a side-tracking, FRN-centric non-sequitur, arguing from the baseless premise of your worthless theory that the reason FRN's are the dominant currency is that people "chose" it as their form of "money". Forget that it was a reasonably sound, prior-existing currency in a completely different form, one that everyone was dependent on, which got later FULLY hijacked. No, in your mind, people actually "chose" FRN's. They preferred them doncha know. Right from the git-go. And why did they prefer them, according to your noodle-brained theory? Well, because they "wanted" something to pay their taxes with, that's why!
No such tax exists today to so to interfere with your choice. Your argument here is specious!
Stop licking windows and pay attention. If you try to use hard specie (e.g., U.S. minted gold and silver coins) as money, the US Treasury that minted those very coins will not see them as currency, but only commodities. You're not "converting" one currency to another, you're "buying and selling" commodities that are subject to various taxes, capital gains being one of them. Likewise, various states will see those same coins, not as money, but also as taxable commodities, subject to sales tax.
Those are barriers to entry.
You're not that daft, that obtuse. You're trolling. I'm pretty sure you knew that already, but I could be wrong. If I'm right, you're just dishonest, that's all. If I'm wrong, and you really didn't know that about capital gains and sales taxes be, then you're incredibly stupid, having missed that to go along with the rest of the knowledge you appear to have.
The people chose their money - this is another fundamental and riveting point Mises made, for it explains perfectly well why money becomes "not money".
How does your argument square with a currency that went from fully redeemable at times for gold and/or silver, to only sometimes redeemable, to not redeemable at all. Was that also a market choice, each step of the way, made by individuals? When a government "chooses" to demonetize a given metal as currency, is that also the "choice" of the people (aka - individuals in the market)?
