How much does it cost in resources to mint, regulate and secure fiat currency?

With my bitcoin lightning wallet I can use money more securely than cash , its private , fees are a fraction of a penny , and I can send and buy things online

Bitcoin is a very useful currency and fiat currency is far more corrupt and wasteful than Bitcoin

I pay a fraction of a penny and get an instant confirmation when I send bitcoin. I spend my bitcoin almost daily as well and it saves me money doing so.

Bitcoin can handle millions of transactions a second today with a lightning wallet , This is what the country of El Salvador is doing when they just made bitcoin legal tender

The amount of energy used has no direct relation to tx throughput on bitcoin and most txs occur offchain with bitcoin. Ask yourself how much it costs to secure , regulate , and mint fiat currency.

Except Spending on goods and services and charitable giving actually increases during rapid deflation(appreciation) with bitcoin

The source is merchant processors like Bitpay and coinbase. Additionally, if you are in the Bitcoin community it is very evident as to what is happening because charitable giving and tips skyrocket and people start buying "lambo's", homes, and vacations during bull markets. One example is Pine donated 86 million dollars to 60 charities during the last bull market - https://en.wikipedia.org/wiki/...

Bitcoin transaction throughput tends to increase over time and merchant processors report higher spending on goods and services with bitcoin during periods of rapid deflation or "appreciation bubbles" thus bitcoin has proven the whole "deflationary death spiral" to be a myth. It turns out that peoples motivation to spend their bitcoin overrides their motivation to save when they feel wealthy, because they are wealthy.

The trend is for less and less private keys to be lost over the years so i don't see this happening , and bitcoin is so divisible, down to 1/1000 of a satoshi, that even if 95% of UTXOs are lost this doesn't effect bitcoin's usability as a unit of account to buy a cup of coffee.

Are you trying to suggest that digital things cannot be useful or valuable? Are you aware that the Bitcoin network is secured by billions of dollars of physical infrastructure that cannot easily be pivoted to another project?

You know as well as I do that most stocks these days do not pay dividends and most of their value is speculative. With gold, most of its value is also speculative. Buying 1 bitcoin equals controlling 1/21 millionth of the network, a network run by people and a lot of physical infrastructure as well.

This notion comes from a flawed understanding of economics. Fiat currency costs at least the same amount of resources to create , regulate and secure as Bitcoin. “Rent” always forces production costs (MC) to always equal sale prices (MR) MC=MR PoS currencies and fiat are simply more abstract and complex forms or Proof of Work that use more human involvement (which uses tremendous amounts of resources and has a tremendous environmental impact) as a PoW coin like Bitcoin. Humans instead of ASICs are shouldering more of the work to create, regulate , and secure each of those currencies; This is "work" whether it involves burning electricity directly or food and electricity that humans consume to perform their work. This is an inescapable economic reality. The more valuable something is the more it will cost to secure it because the more effort will be made to steal and or control it. This applies to any currency or asset.

The amount of hashrate and electricity used in bitcoin has nothing to do with scalability or transaction throughput. Are you aware that bitcoin can already handle millions of transactions per second throughput with instant low cost fees under a penny per transaction?

This same logic would be consistent with stocks , land, homes or any scarce asset. Future buyers are always paying earlier investors via exchanges and they usually hope that it will continue to appreciate in value.
