We sometimes need to go back to the basics, especially during a time of structural crisis like the one we are experiencing now, which has called the principles or our economy into question. We cannot not understand what the “sharing economy” means if we do not ask ourselves what “economy” means. I would stand by this definition: the economy is a human activity consisting of production, distribution, exchange, and the consumption of goods and services. If we focus on the structural changes needed in our current economy, we would have to answer questions such as these: How to produce? Do other ways of producing exist? How are goods and services distributed? Do other ways exist? How and why do agents exchange with each other? Could they do this differently? What is our way of consuming? And is it optimised?
