First off, only a tiny minority of Trump supporters believe the odd COVID-19 conspiracy theory described in the OP.
Speaking of COVID-19 and the unjustified panic that liberal news outlets continue to stoke, the U.S. COVID-19 case death rate has now dropped to 3.1%, which means the survival rate is 96.9%. Six months ago, 3 weeks after the lockdowns began, the case death rate was at around 5-6%. As of this morning, it is 3.1% (6.03 million cases/183K deaths).
Here is a statistic that we have not looked at yet: the number of COVID-19 deaths and the number of deaths from all causes by age group. These numbers come from the CDC's website:
AGE-----COVID-19 DEATHS-----TOTAL DEATHS
0-1 17 9835
1-4 12 1909
5-14 28 2935
15-24 280 18594
25-34 1257 38503
35-44 3401 54563
45-54 9648 100926
55-64 22665 231983
65-74 39980 351806
75-84 48392 430582
85-99 55710 537185
We see that COVID-19 deaths constitute a very small portion of the total deaths for each age group. Among people aged 0-34, COVID-19 deaths account for only 2.8% of that group's total deaths. Even among the highest-risk age group, 85-99, COVID-19 deaths account for only 11% of that group's total deaths.
We also see that 78% of our COVID-19 deaths have been among people aged 65 and above.
So why are some states talking about resuming or actually resuming some of their senseless one-size-fits-all lockdown measures, especially when recent research shows that people with COVID-19 who have no symptoms are far less likely to transmit the virus than those who have symptoms, and given the fact that about 80% of COVID-19 cases involve no symptoms or only very mild symptoms.
