That's only a viable strategy for handsome gang. He is right by saying it's difficult.
Average gang and ugly have absolutely horrible odds doing that. Might literally run through 200 women to get a yes from that strategy within the general population of women. You also may get a yes, but not from a woman you actually want.
There is all sorts of things everyone that's not handsome gang gotta do to get a yes. This ranges from being a conversationalist, to being witty, to dressed to her niche type of dude, approaching at the right time, approaching in the right place, dealing with her friends, managing her emotions, etc . Game is a pretty complex thing.
Handsome gang can throw all of this into the trashcan and rely on their face card and then condescendingly say, "look , I did it. Just be yourself and say hi. See? It's easy".
