"...it can't be shut down."

What prevents BlackRock, that has a controlling interest in ~90% of stock corporations of the world, including those that own the cables, radio transmitters, and satellites that enable global communications, from refusing to transmit any BTC transactions?

"...it's pretty presumptuous to assume we are already in full blown scam mode."

I submit that is the only mode.

"...a sophisticated audience such as mine..."

I can only assume you mean other than me.

"...it costs less than 50 cents to move an unlimited amount of BTC from one wallet to another."

Is there some means I am not aware of that prevents miners from stepping on transactions now? I confess I haven't been attentive and sure could have missed some regulatory or other method of compelling transactions to be included in blocks. I recall back in 2017 transaction costs hitting ~25%. Is that not entirely at the sole option of block producers to this day?

Thanks!
