On some level, this is basically "capitalism 101." If I don't need my resources now, I can put them to work so that I can later benefit from them. This leads to me having productive assets, which pay me some return.
If I could not acquire productive assets, there would be much less reason to save. And it's unclear how one would save, as banks would likely not exist either. You can solve this problem somewhat by having a centrally planned economy. But then you have the problems that hit those.
