I think Satoshi Nakamoto took two things into consideration when creating Bitcoin, so no one could easily manipulate the safety / price of it:
Price and safety are two entirely different concept and when it comes to "manipulating" them the situation is very different.
When it comes to security of bitcoin, no level of manipulation is acceptable and it has never happened despite numerous attempts such as the scaling "wars" between 2014 and 2017.
But when it comes to price, it can be and has been manipulated. The numerous unreasonable jumps and the unreasonable drops are clear indications of that. In case of price manipulation a degree of manipulation has always existed that has not been dominating the market and we get accept it. Otherwise if the manipulation was dominating the market, that could affect the security too.
2.) The not-easily changing offer and demand of primary energy prices and by that a relatively stable energy costs [€/Ws].
I think the recent events affecting our world specially in EU are a clear indication that it is actually very easy for the cost of energy to skyrocket.
So all in all is the equivalent value of Bitcoin, just as the equivalent value of US-dollars once used to be gold, is: Efficiency of computers and energy costs.
This is a naive interpretation of how money should work, in my opinion, that comes from the traditional form of money namely fiat currencies that have no supply limit and keep being printed while the governments try to justify their value by claiming they are backed by something whether it is gold or something else like oil (Petrodollar).
Bitcoin broke free of these traditions and naive interpretations of money. It has limited supply and its value comes from its utility hence determined by the level of adoption it has.
As a matter of fact the cost of production is also affected by the price not the other way around.
I'm not suggesting your arguments are completely wrong, but I say things like energy cost, computing efficiency, etc. are some of the factors contributing to bitcoin value.
