Most of us take out loans to pay for a house that has already seen its best when the money is finally paid back. Or rent a house and pay a hefty sum every month. Yet the best, most healthy and durable building materials are often very cheap or free.
How amazing that we can build houses without loans where numerous future generations can still live in after we die. What a gift to give children. A free house that is still almost as good as when it was first built. With possibility to modify things without machines, a lot of money or craftsmen.
Nature provided us with all we need. We just got so used to buying that we forget the gold that is provided for free.
