While it's commendable to strive for ethical options to purchase human labor, the argument that Bitcoin has no value beyond trading convenience is flawed.
Bitcoin has properties that make it a valuable asset in its own right, such as its decentralized and secure nature. It's also important to note that the value of any currency or option to purchase labor relies on confidence to some degree. Confidence in a currency or option is built upon its track record, its ability to retain its value, and its potential for growth.
Furthermore, your argument seems to suggest that fixed cost, fixed value, and globally fungible trade media is the ideal solution to all economic problems. However, fixed value systems can lead to deflationary spirals that can be just as damaging to economies as inflation. Additionally, your argument overlooks the fact that economic systems are complex and multifaceted, and cannot be reduced to a single solution.
Finally, the notion that Bitcoin is part of a grand vision where only a few own all the top tier Bitcoin while the rest of humanity trades among themselves with lower tier fractions is not accurate. Bitcoin is divisible to eight decimal places, and anyone can purchase as much or as little as they want. It's also worth noting that Bitcoin is not controlled by any single entity or group, but is decentralized and open to all.
While striving for ethical options to purchase human labor is a noble goal, dismissing Bitcoin as useless and placing all economic hopes on a fixed value system is not a sound argument.
