Some 3 person families will be fine living in a 512 square foot home. That's not too uncommon globally. For a family we could also have double or triple sized units if that's what people want.
The units I portrayed are nothing like dorms and they are not apartments, so you probably didn't actually read it. Anyway it really doesn't matter what you think. Since this whole concept is in fact a new idea, it will be quite hard to market and easy for the average person such as yourself to dismiss.
I think you need to work on taking criticism on your project. No matter how right you may or may not be, dismissing the average Joe and claiming that he's just too simple to grasp the concept is only going to keep things difficult for you. If you want to be successful, your average customer is going to be an average person, and you'll have to meet that person where they're at, not yell at them for being too dumb to understand your brand new concept. Doing that is a stereotypical sign of severe self-delusion.
If your site cannot explain the concept in an approachable way, saying "you're just too dumb to get it" isn't going to help. If you find that you have to say this to someone, it means that YOU'RE the person with the communication problem, not them. This is a very important principle to understand as you seek to gain traction for your concept. Instead of blaming people for their opinions, understand that this is a real, organic impression of the project and that it's likely representative of what at least some random segment of the population is going to think. You'd be wise to note the concerns and work toward addressing them.
I didn't read the full page word for word, no, but I did spend a good 3-4 minutes skimming it, and I watched the embedded video, which is much more than most people who come across a random website do. Please find a good mentor who can help you take criticism without being dismissive of a potential customer who is providing feedback.
You didn't take enough time to really understand it as evidenced by your comments. You were dismissive and disrespectful, and have continued that in all of your comments.
