Hey! Let me pick up a rock and let's buy it from each other...

Isn't it the same as any other kind of item that you are willing to sell? It's just the price deemed to have value over an item. Just like paper money, it has value because we say it has, like $100. It's always going to be like that, and that's what humans do. The analogy is quite hard since rocks necessarily have a different function than cryptocurrencies, so it's different but has value because that values it by the demand.

Matter of fact, let's do just that for the heck of it, see how far we can go with it. I'll pick up a rock and call it Akorn and put it up for $10. I'll buy it back for $10 and let's see how much it'd be worth by the end of the year.

Something will be valuable when everyone also sees the same value of that thing.
You may call it Akorn or whatever that is valued highly in your opinion, but when the people don't see any value in it, it will mean nothing.
That is why we need to similarize the things to be valued around the world and the same perception.

Uhh, OP learned how barter and fiat money works? That's cute, at least people now knows about the basics of how we put value on something base on trust. My point is that OP, you are saying that bitcoin was valued on how we deem it's value is but you forgot the fact that that's how almost anything precious has been traded a long time ago.

Trust wont really be that enough since there are lots of criteria's need to be considered first  before a certain thing would be having value and imagine on how monetary system had started from

those old days comparing to now which it starts out to be a barter system until those coins or money had been the start.Its a common concept and as we do go ahead or

technology do enhanced then its just normal that we do upgrade as well in terms of financial system.

If someone really buys the rock that you picked, let us know we have tons of it in our backyard, I could dump mine for $0.0001.

But try selling Bitcoin, you will see how much people would bid for it because BTC is different from what you have understood. It's not a rock that you think is wothrless. It has gone up not just for nothing. You have to learn how rare BTC compares to rocks or even compare it to other altcoins.

Who said you can barely buy nothing with bitcoin? There are many online stores that accept Bitcoin as payment method. Some of which accept only cryptocurrencies. I've also heard of coffee stores (not online) as accept Bitcoin (and some other crypto) as payment method. Bitcoin is striving to come up. And if we do our best and support it, Bitcoin and so many other cryptos will serve the payment purpose.

maybe for now if you take the stone you quote from behind your house, and you try to offer it to everyone, I'm sure you will be laughed at, but for now try to sell a little bitcoin that is in you, with a little price cheap, of course people will not think long, and will immediately buy the bitcoins that you offer, but if it is a stone problem for now, people will not be interested in jumping in, and follow your advice..
