I've also had people try to convince me of bitcoin's infallibility by suggesting that even if the Internet went down, tokens can still be printed out on pieces of paper or have remote processing facilities to complete transactions. If I was a tyrannical government, I would attack these crypto's where they are the weakest and most vulnerable: electricity and the physical infrastructure.

When I researched Libra and found out that the corporate empires are gathering together to back this project, red flags went up all over the place. Your point is a good one as most people are still dependent upon the corporate empires to provide the goods and services they need or want. Hence the strategy of providing for ourselves, rather than being dependent upon them.

I agree with you @zoidsoft. The majority of the cryptos could indeed be relegated to the black market. If people are wise, they would be watching the Libra project with a microscope! It could have a huge impact on how this whole market place unfolds over the next few years.
