I just don't see why someone would give them stocks rather than cash the stocks in first and give them cash
You've heard of RANDCAM, right? Plus, if I were to have the WTS in my will, I could easily have them be the beneficiary of everything I've got. Cash, stocks, gold, whatever. It goes to the WTS for them to do how they please. The same way if my parents were to leave me their house. They are not going to sell it first then give me the proceeds when they die. They don't know when they're going to die. I get the deed to the house. If I want to sell it, it's up to me.
