I think the point to be made is that government bonds don't have any collateral baking them. For example, if a corporation has secured debt, the holders of those bonds might get first liquidation preference-- if the company can't pay its debt, the company's assets are distributed to bond holders, so you get something back. Governments have assets, but since they also have central banks which can issue dollars, in the even of a default, it seems far fetched to think government bond holders would claim government assets-- instead the central bank would just dilute its currency. This was not the case by the way in the gold standard, where government bond holders could redeem the dollar bonds and then also redeem them for gold, which would still have value outside of the failed state.
In any money system, maintaining fungibility is really important. You wouldn't want the distant history of a bitcoin or dollar bills to be of concern to someone transacting with it. You could probably say something similar about dollars, for example there is the famous finding that 25% of US Bills have traces of cocaine on them [2]. This doesn't make me personally feel like by using dollars I am providing liquidity to drug cartels.

Also, 5% is not really significantly more than the typical fee an ATM already charges.

My belief is that illegal speech is also still a form of censorship, just one that we are OK with. And that spam is more like a denial of service attack. Blocking spam is not about blocking the expression of an idea, but making sure that a communication channel is not abused as to make the channel ineffective.
Spam Blocking = you can't say X more than Y (>> 1) times
While technically censorship, there is a big difference, I think. Obviously in practice spam blocking could maliciously or accidentally be used for censorship.
Again, you fail to understand that the number of a machines that find a block could be changed by making the blocks smaller. You could do that by also reducing block size to keep the total number of transactions the same. But the larger point is that mining pools make it so that mining machines are paid for partial work, even without finding a block. This enables the utility of mining to be measured by hash rate, rather than by number of blocks solved.
You called it a gray goo style positive feedback loop. It is not, there is a upper bound on how much will be spent. There is no feedback loop as well, if the price goes up, more will be spent on mining, but that does not feedback to make the price go higher as required for a loop. Moreover, the block reward is exponentially decaying.
Your reading of the tweet is that a person saying a system should use less CO2 implies that person believes the system is unsustainable. I don't think that is reasonable, e.g. an Airline CEO launching an initiative to reduce the airlines CO2 usage would not believe that the airline is unsustainable. I did misread the other part of your statement-- you said bitcoin is ridiculous, not that Hal said that.
> The answer isn't "as much as you can afford period no follow-up questions."
You are right, and this isn't how bitcoin works. The amount of mining should be determined by the block reward, market price, and fees per block. Mining in excess of this is not economically rational, and shouldn't happen. So it is not "unlimited security" at any cost"
Where in that tweet does Hal characterize bitcoin as ridiculous or unsustainable?
In the case of flare gas, it is a byproduct of gathering oil that is unavoidable. The oil is economically worth collecting, but the extra gas is not. I think this can be more finely split into natural gas vs methane-- sometimes the natural gas is worth collecting, but the methane never is.
You could argue that there should be laws to force the methane to be collected and used elsewhere as a condition of accessing the oil. That might be overall better. But prior to bitcoin, that perfect solution was not really implemented. In this sense, bitcoin mining of flare gas is a step forward.
Note that the argument is not just that economic value is created by mining bitcoin, but that running the gas through a generator leads to cleaner combustion and thus less greenhouse gas emission than simply lighting the gas on fire. In this sense, the bitcoin flare gas mining operation by itself could be considered carbon negative (again, surely all bitcoin mining is not). The bitcoin mining pays for the generator. So bitcoin mining is giving the industry a subsidy that enables reduction of environmental harm. It is not perfect, but it is an improvement.
What is your source around Hal Finney? I have not heard that.
