The comparisons fall short.

- pixels are being optimised, with displays going closer and closer to true-off all the time

- pixels: even whitespace is important next to information

- RFC: we're wasting a few bits as a tradeoff for less complicated hardware and less processing power. Not sure if applicable anymore, but reserved fields and consistent parsing saved us some power/materials historically.

- SSL provides security and privacy in your communication at a cost reasonable for the outcome.

It's only logical they if we don't need to spend the energy to mine coins, we should stop doing that sooner then later.

And protecting money is not important?

Well so the RFC reserved bits are waste but also a benefit? Maybe the same is true w.r.t Bitcoin mining?

The cost is reasonable in SSL case but unreasonable in Bitcoin case based on what criteria exactly? Remember that SSL relies on PKI that has a lot weaker security guarantees (see Symantec, DigiNotar and your favourite Chinese CA in your OS's trust store).

Next to nonexistent cost per connection in standard case of SSL. We can saturate gigabit links using modern hardware with AES-NI. Outside of special deployment cases, the cost is a rounding error. We can't provide this capability in a cheaper way at the moment (or we would do that)

On the other hand, we've got Bitcoin which chugs energy/money by design, while other solutions like proof of stake / space / ... exist and are much more energy efficient. People concisely decide to burn money to keep this system running - that's why it's unreasonable.

They are only proposed solutions, not implemented in any existing systems so it's not fair to compare them. Proof of stake for example has numerous drawbacks: https://en.wikipedia.org/wiki/Proof-of-stake#Criticism

Filecoin did some good improvements in cpu/energy usage and PoSpace
