Even if you're able to make that work on an individual level (never buy a home, don't get higher education, make sure you don't need a car), you can't make it work on a societal level.

If you want to contribute to supplying houses to people, you need to build the houses before you can sell/rent them (mostly). That means you need to take up a loan to pay for everything involved in building houses. Then you can sell/rent the houses to individuals that don't want to take up loans. Regardless of whether you personally ever take up a loan, you likely wouldn't have housing without someone doing it (unless you live on a family farm from waaay back), because the people that built it needed a loan to do so.
