You raise a valid point about the importance of having an economy that is sustainable for all people on our finite planet. While Bitcoin may be sound money, it is only valuable if people are using it in ways that benefit society as a whole. Austrian Economics emphasizes individual freedom and choice but at the same time, disregarding social responsibility can create problems like worsening economic inequality and environmental damage.

A closed-loop economy would ensure that resources are used efficiently and sustainably to meet the needs of everyone without compromising future generations' ability to thrive. It's essential to consider not only individual freedoms but also how those choices impact others' rights to life, especially in cases where natural resources are limited.

We need innovative solutions like blockchain technology and decentralized finance (DeFi) platforms that promote equitable access to financial services while reducing waste production, energy consumption & carbon footprint. By leveraging new technologies responsibly with consideration for their wider implications we can help create a more sustainable future together!
