Your numbers are a bit off. Google tells me that s19pro price starts from $17,799 and each can produce 110 Th/s that means to get ~160 Eh/s you need 1,454,545 which costs $25.88 billion not 2.
You've missed this part:
Updating this, the price for miner stays the same as that's the cost to manufacture it, not what the current market pays for it
Video cards go for 3 times the price now that doesn't mean it costs NVIDIA 3 times more to produce.
That's the price bitmain was selling it before the surge in mining profits, that's the real price of the equipment!
You are also forgetting that just owning ASICs is not enough, they have to be run and that requires a tremendous amount of electricity. So basically the malicious government has to shut down their country (or a big part of it at least) to mine bitcoin with their 1.45 million ASICs!
Wait, are you saying that bitcoin mining is energy-intensive and rivals a whole country activity, of people eating, going to work, having fun, watching tv, and making transactions? Infidel!
Not to mention that the cost of this electricity is also added on top of the cost of the ASICs.
That is about $390k daily per ASIC which $560 billion for all 1.45 million ASICs per day for 5 cent per kwh.
An s19pro burns around 90kwh of power a day, at 5 cents that are 4.5$, for the global network would be close to 6 million a day.
Not to mention that with 20% of the hashrate you would be making $10millions
in profits from mining a day, a fact you completely ignored.
Now, are suddenly closer to trillion territory.
No, we're not!
P.S. Getting current hasharate is 160 Eh/s to have 50% of the hashrate you have to have 160 Eh/s
P.S.
You're again ignoring the numbers in my scenario and it's a bit...you know..
Updating this, the price for miner stays the same as that's the cost to manufacture it, not what the current market pays for it, to make 20% with a current 160exa you would need about 300 000 S19pro, that would be just around 750 million,
The money may not be the issue but the logistics for manufacturing an equivalent of 10 years output of all the miner manufacturers would still be significant.
10 years? More like 4 that counts and probably that one split in half due to faulty equipment and low hashing power of the older batches.
In 2014 (7 years ago) Bitmain released the S3, it was doing just half of TH/s, at that time just 1000 modern miners would have been able to launch a 300% attack
