Very well thought out and I didn't have much to counter as well.
Televisions, aeroplanes,
Christmas lights, plastic, all require enormous amounts of energy to be produced and used: what is the amount of energy considered excessive to produce them? Why is this calculation done for Bitcoin and not for other goods?

You're comparing Bitcoin to its substitutes instead of the various other human activities which could produce significant carbon footprint. Heck, I can think of tons of activities that directly contribute to an increased carbon footprint; transportation, chemical industries, etc. Does that mean that we can just stop producing metals, refining fossil fuels, completely eliminate them from our lives? Probably not.
In comparison, when you're talking about Bitcoin, the adoption currently is far lower than most of it's substitutes. At 7tps, there are tons of other payment methods that easily outpaces this by a factor of thousands without a strain on their network. Can people stop using Bitcoin? Probably, there are other payment methods because really, do the majority of the people absolutely care about decentralization, transparency? I can see an argument for this if your transaction volume rivals them but if the benefits is still fairly limited, then probably not.

What about the e-waste that is constantly generated from Bitcoin mining? The competition makes it such that old ASICs are always phased out once the profit margin diminishes and as ASICs can never be reprogrammed into something else, they usually end up being useless afterwards. Of course, they're always turned on 24/7 with the chips pushed to their limits and the failure rates can be higher than most electronics. Surely both the production and disposal of these ASICs are fairly detrimental to the environment?
