Agree with above, if you're not coastal, might as well be in Nevada or Arizona.
This is my first year out of residency, I live 1 mile from the beach, renting a house in SB. After riding my bicycle home, I run through a nature preserve at the end of my street and in a few minutes, I have to choose if I want to continue along the top of 200-foot cliffs that look out over the Pacific or descend the steps to run along the beach. Typically I run into more rabbits and storks than people. The air here is clean and the traffic is minimal, although I don't really care either way about the traffic since I commute by bicycle. That's not my problem.
Honestly, I love it here and I could care less what anyone else thinks about it. If anything, I am grateful that the high taxes and other downsides scare so many people off. SoCal is crowded enough without more people. There are plenty of fantastic places to live and we all value different things, so to each their own.
