...as of now. As long as we have ISP's who grants us access to the internet, or any part of that internet, hardware-wise and otherwise, is controlled by any central authority or produced non open source.
Don't get me wrong, I love what is going on. BTC and friends are shaking up the world monetarily and the potential for a future where traditional banks and their power over the little people (that's 99.9999% of us) are no more. It is a light in the tunnel, if we can keep our eyes from being fooled by the artificial lights designed to lead us back into the darkness.
But. As long as we rely on any centralized system, crypto can not be truly decentalized. How do we solve this? What is the next step towards true decentralization? A world-wide cascading network of long range radio devices (HAM, LoRa, etc) that people can assemble and program themselves?
What do you think? Or are the fundamentals I presented above faulty? Please let me know!
You need to detach ISP's from crypto currencies, ISP's are not inherent to cryptocurrency. Yes, an ISP generally stands in the way of you and sending crypto, but by inherent nature cryptocurrency does not rely on an ISP, so it's not a productive argument to make.
Take it one step further from ISP's. Who controls the ISP? The government. You could argue that crypto isn't decentralized because you might live in a jurisdiction that proposes crypto taxes or strict regulations on any sort of trading. Again, governmental intervention isn't an inherent, by design, property of crypto, so you wouldn't correct in making that argument.
Your fundamentals aren't faulty, because you essentially make the case for free and fair internet without purview of the government. But tying this to bitcoin isn't the best application of your concern. It's comparing apples to oranges.
