Just to get my 5 cents in (as an ex-barista), you can get the best (single origin) coffee's in the world for between 8-12 euro's for 250 grams.(there are more expensive Geisha coffee's, but that's really hi-end) Lets assume you use 18 grams of coffee for a cup. That yields you at least 13 cups of coffee (from the 250 grams. Raw resources would cost you between 0.62 to 0.92 euro a cup.

Manual ceramic grinder between 30 - 45 euro's Aeropress about 35 euro.

Both of them last at least 5 years.

That is quite a bit less than the 5 dollars. Yes it takes you about 5 min to brew a cup. But from having worked in a espresso bar for many years, during morning rush hour, you would be happy to get your coffee in less than that.

I think the article is interesting, because it deals with culture. First is the, go buy a cup of coffee at starbucks culture, and pay premium for the coffee. What I've noticed from working it's that people have their rituals when it comes to coffee. It's about getting fuel to get to work. It's about taking a break from the environment they were in 5 min before. It's about comfort.

That is what you get for the 5 dollars in the article. It's not only about the coffee, it's about taking a break, rewarding yourself.

If you can find a way to get the above pleasures from home-brewed coffee, or stop drinking take-out coffee. Great! But I agree that only seeing it "5 dollars not used for your retirement" is really short-sighted. There is a deeper problem if that is the difference between you able to retire when you're 65.
