If you can do both at the same time, or get basic classes out of the way in the summer at a community college, then it may be ok.
But delaying electives for two years would put you at a significant disadvantage in technical fields, imo. Not to mention the basic classes (math, physics, etc) will be a joke at a community college so you will have a weaker background.
I took some community college classes in high school through a program we had with them. The environment and students were very underwhelming. Your mileage may vary.
I got to take relevant classes (CS) in my very first quarter of college. The first two years it was a 50/50 split. The biggest benefit was being among smart, interesting people. College was way better than any previous educational experience, by far.
That being said I didn't experience waiting for core classes. The class sizes were typically very large though. Taking these on the side at a community college while attending a 4 year college sounds like a good idea. I'm just opposed to putting everything on hold for 2 years to do basic classes. I don't think a community college is the place to explore interests.
I don't think you read the article. It's telling people to defer a year because of coronavirus, not the usual college is not worth it schpeel.
That being said, I disagree with your advice in two cases:
1) Most top schools offer free tuition if your family income is below a generous threshold (like $150k). If you can get into Stanford and meet this criteria, it's cheaper than your local community college.
2) If you are studying a technical field, even if you are average, a degree has greater ROI than just about anything else. You can pay off your debt in the first few years out of school and continue earning dividends for the rest of your life.
If you are an average student and studying a non-technical field, then the decision is not as clear.
