The internet gets locked down all the time. However, what I said was prevent BTC from being transacted in. They don't have to end all comms. The Restrict Act actually is a mechanism to prevent encrypted communications, and that is all that is necessary to end cryptos.

Maybe a couple people could transact via radio yearly given extant capabilities. Not enough to create a functional economy.

Note I am not against having a functional economy. I depend on it as much as anyone. I advocate it as much as anyone, too. However, it is unproductive to want something and not do anything to get it. Given that BTC depends on mass communications enduring, folks that seek to enable BTC to flourish need to create mechanisms by which communications can endure, including those that transmit funds that legacy financial interests don't want them to transmit.

I seek to encourage folks to walk their talk. If you know of Teslan free energy communications mechanisms now is the time to enable folks to use them. If you don't want to be targeted for patenting something, don't patent it, or patent it in the name Satoshi Nakamoto, or something. It takes time to build out infrastructure, and I don't think there is any such physics as you suppose there is. We need to employ it, if there is.

We need something, or we're only going to be transacting locally. If we have to move to Qortal or Beechat we should be getting that gear and using it now, while making and acquiring such hardware is far easier than it will be after something like the Restrict Act is in use to prevent uncensored communications, because they'll act to prevent avoiding their Act.

Wishful thinking is the enemy of productive action.
