You are completely wrong, my wife is a pharmacist in Texas and pharmacies have great latitude in their decision to dispense, deny, or consult with the doctor, and often cause the doctor to change the prescription. You can always go to another pharmacy if you don’t like their decisions.
In some states, they can prescribe some medications. In Texas, pharmacists are licensed by the state pharmacy board, the members of which are selected by the Governor (so there is political oversight directly accountable to the people). Pharmacists control the flow of drugs and work directly with the DEA to prevent drug crimes, but primarily are specialists that prevent drug interactions. There are thousands of possible complicated interactions that doctors are not expected to know about because the science is always changing and it takes a dedicated professional to stay current with. This is why pharmacists are part of the medical health apparatus and not just a pill counter drone of your local convenience store.
Specific to Op's post, the state board of pharmacy (again, an accountable bureaucratic body whom you can vote out by changing the governor) made policy when hydroxychloroquine was announced as effective to keep the supply limited to existing patients/diseases (without the pill many would die) to prevent doctors and others from hoarding the supply as a potential covid treatment. Personally, I think the supply shortage is over, and the board should open up prescriptions to covid patients, and the way to do that is to get the Governor to force a policy change. Again, this is not up to your local pharmacist, so don't yell at them over something they can't control.
