The quantum computing concern has more to do with the ability to derive a private key from a public key and move coins.

While it could also have impacts on mining, the primary concern is that of security of value stored on-chain.

Nah you're right mostly.

I think more so that someone with quantum abilities would either have to choose do either

a) attempt at using it to gain vast majority of block rewards

B) use it to attack adddress and derive the private key from

A is a moving target, b is a static one hence you'd be more effective at the latter and not as effective at the former.

But BIP 360? I believe it's the bip assigned to QUANTUM resistant bitcoin addresses.

What really has me scratching my head is the zero point energy stuff. If energy is free ( mostly from the Malaysian airflight videos making it highly plausible that it is) then how do we negate the cost to attack the network itself being a costly one of it would only be costly in hardware and not both hardware and energy. Just thinking about this one, not saying it is true, but the whole thing has me thinking about what if someone had free energy like for real.

Just on the energy thing, energy is basically free and massively abundant in the world as it is (the sun everyday for example).

The resource we crave isn’t energy but power.

Hydrocarbons are the best fuel as they’re portable packs of power. Solar batteries suck as pound for pound pack less energy (abut 100x less) than HydroC and aren’t as portable. HydroC are the ultimate power “energy resource” for individuals (and thus society)

Quantum computing would also have to have the ability to consume power (or magically harness the suns energy) which currently wouldn’t be there on a large scale to meet their demands, thus will be limited in its function until its energy demands are met

Unless the worst people in the world somehow manage to gate keep it for long enough, its likely quantum computing will be used to defend bitcoin and not destroy it.

I hope what im saying makes sense

You still have the cost of acquiring mining equipment. Free power can drive down costs, but the real mines and the chip fab are not free. You can talk about free energy, but there's still a cost to harness it.
