The fees on the main chain are ridiculous right now so that is also very true. 
Privacy… I’d rather be secretive. They can see what happens on chain. Ok cool. Good for them. I want them to see it. They just won’t know that it came from me because I keep secrets. Like a bank account. We keep secrets of how much we have or don’t have. We don’t tell the cashier. I have x amount of funds so this card should work. We just swipe the card and keep it moving.
