There's a lot of quackery around these days, especially with regard to tech and finance.
There's quite of bit of quackery just with nutritional supplements, too. And people and companies try to bypass the FDA all the time with fake cures, the COVID-19 epidemic was just the latest version of that.
The FDA is over-zealous with their testing requirements. However, without them we will see an explosion of fake cures for everything. The legitimate pharma companies will lose money, or otherwise start cutting a lot of corners in the pursuit of profit.
We need something like the FDA to keep things in check.
