Possibly one of the worst takes I’ve ever seen.
If you’re doing bridged networking on your laptop with VMs, they should get addresses the same way the laptop did. If not, you’ll be doing some pretty application specific networking anyway which is an entirely different argument. Basically nobody says “ipv6 must never be NATted even in test networks etc” - people don’t want NAT-by-default architecture and none of these scenarios change that.
An LED (or photodiode used as one) is a fairly simplistic device compared to an assembled receiver / transmitter. Just like you can burn gasoline in a car but you can’t push a car to turn the engine to make gasoline - it’s a complex system that really only works one way.
if you invert the flow of electrons, a receiver becomes a transmitter
Ehh not really. That’s kind of like saying if you invert the flow of photons, your eyes work as flashlights.
“It could be possible with some changes” the changes would amount to removing the receiver and replacing it with a transmitter. In this specific case I’m not sure if a transmitter already exists at this antenna and it’s definitely possible one does, but that’s not a guarantee at all
Not by “simply reversing the flow” it can’t. You’d need to remove and replace many components, just like the example of changing an Rx to Tx system
