Nima Arkani-Hamed makes a good point that there would be no large objects around, if it weren't for the large ratio between electromagnetic and gravitational interactions. Everything would collapse down to black holes.

@BartoszMilewski How do you get a unitless value out of that comparison?
@BartoszMilewski Then I dispute the "large" part without disputing the outcome if it were smaller. I can just as well say that electrons have a very large charge.
@robryk That's just another way of putting it. We are surrounded with gigantically charged elementary particles.
@robryk You just consider "typical" matter around us, made of protons and electrons. An atom is theoretically bound by both electrical and gravitational interactions. You look at the ratio of the two.
