You're creating a bunch of straw-men, and intentionally misreading the sources.
Another fact is that SARS-CoV-2 is not human-made.
Meaning it was not genetically manipulated. BUT it was studied in a lab, mutated there, learned to adjust to human hosts, and then escaped.
Have you got a different source that says the virus was created in a lab? The one you provided clearly says otherwise.
Just a straw man. It was not man-made, but it likely DID escape from the Wuhan lab:
"Also recalled that samples (blood and thymus tissues) from the miners were sent to the Wuhan Institute of Virology for research purposes. As their labs were under construction at the time of sample collection, virologists may have begun experimentations in 2017 or 2018, Dr. Latham and Prof. Wilson said. Then the virus may have leaked from the lab by accident."
That article is about pre-existing T-cells reactive with the virus. It says:
Straw man, again. It's clear from the evidence shown that transmissible is far below what is expected from the standard models, the one Fauci seems to think is unassailable fact, but doesn't work with COVID-19. One theory is pre-existing T-cells, but none are confirmed.
Why did you not address the salient parts of the article?
Taken together, this growing body of research documenting pre-existing immunological responses to SARS-CoV-2 may force pandemic planners to revisit some of their foundational assumptions about how to measure population susceptibility and monitor the extent of epidemic spread.
“The conventional wisdom is that lockdown occurred as the epidemic curve was rising,” Gupta explained. “So once you remove lockdown that curve should continue to rise.” But that is not happening in places like New York, London, and Stockholm. The question is why.
Sure, there are multiple theories as to why, but the fact is, it's happening.
While most experts have taken the R0 for SARS-CoV-2 (generally estimated to be between 2 and 3) and concluded that at least 50% of people need to be immune before herd immunity is reached, Gomes and colleagues calculate the threshold at 10% to 20%.
Here are a few more references showing that Fauci's reliance on the 1970's model based on the HIT=11/R0 formula is wrong for COVID-19:
Individual variation in susceptibility or exposure to SARS-CoV-2 lowers the herd immunity threshold
Why herd immunity to COVID-19 is reached much earlier than thought
