While I agree with your broad point, the attack rate you quote is based on a selected sample; patients with symptoms and travel to high risk areas or contacts of infected patients. The overall attack rate is maybe 4000 (1221 who were diagnosed based on symptoms plus somewhere between 2-3000 undetected cases based on the random samples)/364,000 or about 1.1%.
That unfortunately is not enough herd immunity to make much of a difference.
One other datapoint, the town of Vó, Italy, where all 3000 residents were tested and 95 tested positive (attack rate of 3%). It had 1 death, so an IFR of about 1%, but very small sample size.
