Most of the country isn't as congested as Palo Alto. Yes, If I'm leaving a congested spot and could straight ahead join a great instrument approach to a different runway/airport, that's what I would do.Lots of people say that.
It's quite wrong. Returning to your starting point involves a lot of doubling back, a poor choice with an emergency if you have any alternatives.
If I have an emergency in IMC leaving Palo Alto, I'm not returning to Palo Alto. I'm lining up with San Carlos or San Francisco if I have enough power to get over obstructions, and landing in bay mud otherwise, while avoiding Facebook. If pigs are flying and 13 is in use, I'm landing at Moffett.
At a minimum for the rest of the vast country, I make sure I can get back into my departure airport.
