Is it weird to spend 6 years at a community college?

Dude! Take it from someone who has been down your path already. You will NEVER regret getting into the math and physics. At 22-23.. you're still just a kid with lots of time ahead of you. Don't be in too much of a hurry and don't let education get in the way of your education. Chance favors the prepared mind and you don't learn everything you need to know about life in school. You will find the extra few years will be a great benefit to you when you get to UC. Good luck!
