Why? There's a really simple procedure that can solve these problems:
Don't hit on, feel-up, or try to have sex with people you're in a professional business relationship with. That goes double for people you hold power over (managers to employees, VCs to Founders, etc).
If you're really truly worried about false accusations then here's another fix you can have for free: record your meetings, texts, emails, and calls with founders and/or don't meet alone.
I expect smart VCs that are interested in making money (as opposed to lording it over others or using their position to get sex) will continue to take lots of meetings with women.
