What other people? The ones who have no medical degree and zero acquaintance with life in the malarial Third World? Half of them even think ivermectin is used to treat malaria (it is not!).
If you don’t believe Dr. Noble, how about the published studies I posted above? Do you think all those researchers are lying and snickering?
Something I left out, and really should be brought up here, considering all the folks singing the praises of HCQ and how “safe” it is. While it is a relatively safe drug and has a lower incidence of side effects than its older cousin chloroquine (and, sadly, less effective), it does have its side effects, some quite serious, and the risk is cumulative over time. I, myself, would never take it long term unless I had rheumatoid arthritis or lupus, and under a doctor’s supervision with regular testing. I would take it short term if I had chloroquine-sensitive malaria, of course.
One very practical reason (among others) people who live in malarial areas is the unpleasant side effects they can have, usually gastrointestinal.
There is a very real risk of vision loss from long-term use of chloroquine and its cousins, not to mention cardiovascular damage. Better to take your two-week course if you contract malaria than to risk the side effects of being on it long term. (And to my mind, better to risk Covid or the vaccine than to take it for however many years as a preventive measure, especially now that we have treatments that are actually effective now like monoclonal antibodies.)
In some countries, workers (forestry, for example) and military personnel are issued antimalarial drugs for prophylaxis for limited periods when they are required to work in especially high-risk areas. Foreigners in country for a limited time often take them to prevent malaria as well. Normal citizens do not routinely take drugs as a preventative (treated window screens and mozzie nets are good, though).
Now for the risks of taking chloroquine (CQ) or hydroxychloroquin (HCQ) long term.
Ocular toxicity: CQ has a higher incidence of ocular toxicity (2.6%) than HCQ (0.3%). After 5 years, HCQ risk for retinopathy is 7.5%. Risk continues to rise with every year until at 20 years, risk is 20% and continues to rise at a rate of 4% per year thereafter. Not nice odds. No wonder no one takes this stuff long term unless they are suffering from rheumatoid arthritis or lupus.
Cardiotoxicity: Information appears to be somewhat spotty on long term use, but it looks like cumulative dose increases risk (same as for retinopathy):

Check out this post regarding a doctor in Virginia starting a lawsuit because his health care agency will NOT let him use Ivermectin. https://freerepublic.com/focus/f-chat/4014331/posts
I then found this link from 2011 on the wonders of Ivermectin and posted it and some long quotes at the above FR post. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043740/
After seeing how many people worldwide and in Africa were being treated with Ivermectin, I now wonder if the low rate of Covid is because of frequent treatment with long lasting Ivermectin, rather than with HCQ malarial treatment? In 2011 the article reported that a billion people in 80 countries needed help with Elephantiasis.
