Yes, it is a business, and with low barriers like restaurants, you will have as much luck gaining an edge as in restaurants. Some people will manage to make large "chains" by figuring out how to improve the technology of buildings itself, while most will eek out a meager living for the huge risk burden they take on a bitcoin standard. Most people will not be in the real estate business because it is inherently low ROI.

Most people will not be in most businesses that they know nothing about. The fuck do you know about real estate? Do you know the difference between a blue-phosphor-pump and a violet-phosphor-pump LED? etc.

This isn't esoteric or insightful, but like managing real estate today, fiat puts a large premium in people who manage to verbosely say rather straightforward and obvious things that scratch the surface of ideas and are <20% wrong to the choir like Lyn Alden.
