Listen, JayJuanGee, all you really need to know is the further you abstract money away from barter the bigger a scam it is. Since humans practice specialization of labor, monetary units besides direct barter were needed.
The closest thing to barter without being barter to facilitate trade with specialization of labor is the trade of non-perishable physical commodities as money (silver, gold, copper, etc).
Craptocurrency is abstracted WAY WAY WAY the fuck past barter in a dysfunctional, Keynesian, Rube Goldberg machine based on artificial scarcity that claims to be decentralized but has transaction validators that are designed to centralize and with built-in, rent seeking middlemen in every trade that you also have to ask permission to in order to even move your "coin".
O.k... I will use your framework.... except I will presume that we are talking about bitcoin, and not folding shitcoins into such discussion, in spite of your dumbass inability to stay focused on bitcoin, you dumbass convolutor.
Bitcoin is way the fuck less abstracted away than physical metals such as gold and silver, because you can keep your bitcoin private keys within your personal possession if you so choose. Therefore you do not rely on anybody for your security or storage or transportation or verification. Of course, there is a system involving mining, verification and transactions and anyone can chose the degree to which they participate in that system, that has open source transparency regarding how it works including market based incentives.
Your security, storage, transportation and verification of your gold is a lot more complicated, especially these days and into the future when fewer and fewer people are likely going to be involved in such system, especially since they are continuing to be moving towards bitcoin... and you have a fucking BIG ass problem with both divisibility and liquidity.
Even if it was possible to create a decentralized digital currency - it's not, it's 100% impossible -
You don't know what the fuck you are talking about. Bitcoin is the most decentralized of any value storage system that we have ever had, and various forms of math including proof of work and difficulty adjustment help to facilitate the operation of such a system.
it would still be so far abstracted from barter that it would be an obvious Keynesian scam to anyone regardless.
Again.. assumptions assumptions... You want to assume that value has to be physical.. you are a dumb ass. There is value in being able to transfer something across the world in minutes that is recognized as valuable on that side of the world. So therefore, i have just transported value across the world with fairly little extra expense and I did not have to ask for the assistance of anyone because the bitcoin system allows for the transportation of bitcoin tokens on its system and if i have the tokens I can send them to myself, to you, or to somebody else or to multiple people at the same time... BIG or small transferrings of value... which is valuable in and of itself to be able to do that.
Such is the case with anything classified as currency - garbage based on artificial scarcity like US dollars, Bitcoins, Chuck E Cheese tokens, instead of physical commodity money like silver, gold, copper, etc.
Well, whether you say we can do it or not, we can do it.... .proof of the pudding is in the eating, and we can do it, right now today, if we want to do it and we have a party in which we want to transact with, whether with myself, with you, with someone else or some group or institution or government.. they just have to provide a receiving address.... and viola.. it happens today.. it is not a theory except that we are talking about a scenario that can be carried out right now and is being carried out on a regular basis that has been increasing for more than 10 years and increasing more in recent years (we have data on that, too and people are paying for such transactions and usage too.).
It is not hypothetical..except that it is still evolving so how it will be used in the future is likely to merely be an extension of how it already can be used today.
