I think the reasoning to re-raise SC/PP is correct, assuming that you will only 3bet or fold all other hands as well, otherwise your calling hands will be left in a very tough position.

Given that your opponent is abusing the button it is EV+ to 3bet with 15%-20% of your range (including SC, PP) from BB, because of the fold equity.

Tougher question is where is the point when button is opening too many hands. Or in other words, what is the button's PFR% starting from which 3betting with PPs/SCs from big blind is EV+ (given that the button is decent). Probably it's around 25-35%.

Of course, the higher the button's PFR% the bigger range you can 3bet EV+ from BB.
