What's the downfall? No one does this.

There is no down fall.
Food graded diatomaceous earth is the best though

I had a similar problem with my last grow,and found a solution:
Nicotine,which I use when I mix my own vape juice,is poison...(not good for me,but much worse for aphids) So,I mixed up a weak nicotine solution (1/2 teaspoon of 100mg unflavored nicotine to a pint of distilled water) sprayed the aphids,and boom-they were dead...But ,I only had 4 plants so spraying them was not a big project.
You do have to actually spray the mixture ON the aphids to kill them,so if you have 20 large plants or so,it could be quite a job,but it does work-and the nicotine biodegrades in about 8 hours,so no poison is left on the buds.
Just relating my experience,some folks may not be too keen on spraying poison on their buds,but it does degrade in a relatively short time,leaving no taste or toxins behind.

One downside is ,that if you're using ladybugs,it will also kill them,so you'll need to wait a day to introduce them after you do the nicotine thing...
