1. No issues—here is the Euro/Dollar chart for the month.

In my opinion, the trend is clear. Regarding the “wrong candidate,” let me explain: according to market estimates, the person Trump wanted to promote could have simply become a dull executor of Trump's will and effectively turned the FPS into a “lapdog.” There was a risk that Trump would implement his idea of devaluing the dollar.
A short term chart does not show anything, the dollar continues to devalue as planned. It is actually a good thing and aligns with what they want to do in terms of economy and trade. It is weird to single out Trump again for doing something that is a normal strategy, and when some other country does the same you don't talk about it in such a negative way. The FED is already a lapdog, Powell is extremely partisan and biased. The only difference in these things is whose lapdog the FED is currently, that is what changes from time to time.
2. This is solely your personal opinion and your view of the situation. I believe that physical demand, in the absence of supply, leads to an increase in the price of this resource; that's how the market works

That is not what you wrote. You wrote that some arbitrarily picked demand is more valuable than other types of demand because you think so. That is false in any case and has nothing to do with how markets work, or supply and demand. I can even make a claim that certain types of instruments here are in more demand than any of the physical assets that you have given. Most of the consumption of those that you gave is not by choice, it is through secondary means. People are only consuming them as a side effect of what they are actually consuming. Nobody is buying a piece of technology because silver was used to construct it by choice. On the other hand, the demand for Bitcoin and for stablecoins is direct and real. Those that are speculating on it are not part of the consideration, speculators speculate on everything.
Its a good idea to recognize each asset has its own values, FIAT is fractional and of no fixed value though in theory deflation is possible there is a stated inflation target of 2% I believe and that's compounding forever into a dynamic which makes the population poorer. The rich dont hold cash in the majority, they hold assets with the debts and wages they pay in this cheap FIAT cash. The arbitrage effect makes the rich richer and the poor poorer, it is not truly capitalism imho.
I don't think that whether the primary monetary means is the current FIAT or not has anything to do whether a system is capitalistic or not. You can argue that it is actually what confirms it is capitalism, those with skill or with means are able to utilize their own choice to create advantages for themselves in the economy.
Crypto as an asset is not fractional reserve, its a known fixed figure if we are referring to Bitcoin. Even the supply is harshly regulated with only demand swaying either way according to much speculation. These factors do make it very different. We can say there is a small consumption effect, some BTC is lost but Im not sure its a deciding factor usually.
Bitcoin is the only crypto with a fixed supply, all others are directly inflationary as in their own chain or they are inflationary because they keep releasing other altcoins. Also, we are unable to confirm that there is no fractional reserve. It is not possible to do fractional reserve on chain because 1 Bitcoin will always be 1 Bitcoin. But you can do fractional reserve stuff with platforms and ETFs and stuff like that. We can never be completely sure that some exchange or ETF is not creating paper Bitcoin and selling more to users than is available on the platform. This risk is very real today. With silver and gold it is much worse though, a lot of it is fake and it is impossible to run any kind of mass scale audits. At least on Bitcoin we can confirm the supply on the chain.
