Another concept of freedom is that every single person can build a mining rig and try to profit, or just buy any digital-coin and make transactions with it or store it...
...using money that they earned in the current economic system - if they have enough. You need to have a lot of your country's pre-existing currency to buy a decent enough mining rig, or invest into crypto. Of course, if you have a lot of BTC for example, you can use just that to invest, but you have to get there somehow. You can't make something out of nothing.
Let's just disregard the fact that in some countries (the UK being a prime example) your BTC is worthless unless you convert it into the country's prominent currency. Therefore, the concept of freedom in crypto is essentially flawed, as you first have to be a major player in the current economy to have something to invest into your conversion to crypto. If you're a small fish in your country's economy, you'll be a small fish in crypto as well - helping the big fish to get richer. Only the identity of the big fish changes.
Power consumption or any other unfortunate situation like GPU prices is just a temporary face that we must go through. And those who cant see or know the benefits or the concept behind blockchain in general or even in some specific situations its their "problem" -ish. The tech is still in its infancy. Of course not all crypto coins (more than 10,000 currently) are needed or are legitimate and try to help the world going forward...
Are you saying that crypto is good, and the current economy is bad, and everyone who doesn't want to, or just can't invest into an infinitely more volatile system has only themselves to blame for not seeing the benefits? It sounds a bit like a religious statement, don't you think?
Besides, if everybody becomes a crypto miner, then who's going to work normal jobs? You can't maintain a society where 100% of the workforce is a crypto miner. You can't blame the people who are left behind for reasons such as:
- not being interested in banking, crypto, or other monetary affairs,
- not being tech-oriented enough,
- not having the money for a mining rig (especially in the current GPU market),
- living in an area with relatively high energy prices (the UK again being an example),
- not willing to take the risk of investing into a volatile economic system,
- not feeling the need to change, and so on.
As long as crypto doesn't have an answer for these people, it won't change the world. It will only make a few people richer. You can't change the world by thinking only about your wallet.
Freedom is only great until it starts to limits other people's freedom. An attitude of
"I do what I want, and you can help yourself to the leftovers" is not freedom, but arrogance.
