5 of the 6 points noted in OP’s comment had to do with brick’s rigidity and compressive strength. 1 point was related to the environment. Plastic bricks are an alternative to sand/clay bricks. Traditional bricks first appeared in China and have been adopted and used by humans across various civilizations for thousands of years. As engineering advanced globally, the pros and cons of bricks have been well explored and well understood. Plastic bricks are a new contender to this problem. That said, when you have a new contender to a centuries established and globally adopted solution, it might be more likely to prompt exploration of its potential cons. Starlink is a new engineering solution with several of its own cons that have been reported in HN. It is difficult to compare Starlink against other alternatives when Starlink has a narrow use case that it particularly excels in (high speed Internet to unserviced areas of the globe)
