It's really misleading to start spouting bad information like this. My fear is you're telling all the young, impressionable 20-somethings in your life this garbage.

helps you compare the costs of buying vs
renting the same house and when I entered my numbers, it's very close. A more real life scenario is comparing buying a 3BR/2Bath house vs staying in a 2BR apartment. Most people will need to fill that bigger house with furniture, buy and maintain appliances, lawn mower, snow blower, etc. If you take a few minutes to think about it, it really only makes sense to buy if that's the lifestyle you want + you can afford it. Consider also how long you will stay in that house.
I'm not against owning a home but don't go into it without considering all the costs vs the benefits.
