Definitely a good thing to cover, thanks. You may have seen this already but this is the best resource on this topic https://home.treasury.gov/system/files/136/StableCoinReport_...
Based on your reference, I'd say a decision by the SEC to simply audit stable coins would likely collapse the crypto market and could easily trigger a wide market "rug pull" from the exchanges.
In the interest of full disclosure, you may want to just mention this possibility to the beginners.
