You had a positive outcome with ivermectin so all anyone is saying is let's take the next step and do a study on a large group of people with controls in place so we know it is the ivermectin that is working and not some other variable.
The Lancet is a really well respected medical journal. They have a paper here on ivermectin:
The findings:
Among patients with non-severe COVID-19 and no risk factors for severe disease receiving a single 400 mcg/kg dose of ivermectin within 72 h of fever or cough onset there was no difference in the proportion of PCR positives.
There was however a marked reduction of self-reported anosmia/hyposmia, a reduction of cough and a tendency to lower viral loads and lower IgG titers which warrants assessment in larger trials.
So they are saying they need more evidence to reach a conclusion but there is evidence that it may be a therapeutic.
Now, look and see what is in the pipeline for release in the next couple of months:
Ivermectin in Adults With Severe COVID-19.
clinicaltrials.gov
Since there is no specific treatment for COVID-19 and the therapeutic options are scarce, the researchers believe it is completely plausible, urgent, and necessary to evaluate if ivermectin use reduces the risk of admission to an intensive care unit (ICU) in hospitalized adults with severe COVID-19.
The proposal is a randomized, double-blind clinical trial, conducted at CES Clinic, Medellin-Colombia. The investigators will randomize 100 patients with severe, non-critical illness, into two groups, one group will receive ivermectin in addition to standard management and the other group will receive placebo plus standard management.
Clinical outcomes to evaluate will be ICU admission, need for mechanical ventilation, length of hospital stay, days in the ICU and mechanical ventilation, and finally, the incidence of adverse events related to the intervention. The estimated time to complete the study is approximately five months.
All anyone is saying is let the doctors do studies/trials to confirm or disprove if something works. You can search that clinical trials site and see all of the ivermectin studies that are ongoing or close to completion.
