Absolutely not, it's millions of times more wasteful than that. You don't need to allocate a single miner to a single block and then throw it out. It's just so many order of magnitude more wasteful than it needs to be that it's hard to reason about. You should be able to run the entire Bitcoin network on a single Raspberry Pi. It's literally 2tps, each a few bytes.

There's no misunderstanding. The kWh and kT of e-waste don't need to happen, it's just a poorly designed proof of concept that ran amok.
> If mining machines were on average 2x larger and more powerful (but there were half as many of them), then by your argument bitcoin mining would be 2x less wasteful.
No, I'm measuring waste by weight, in kilotons per year. In addition to energy consumption. So if a machine was twice as large it would contribute the same amount of waste in both columns.
