There are many people that believe monopolies are good, or at least that's what they say. Peter Thiel and Marc Andreessen are notable examples that argue monopolies are good for innovation, as they supposedly allow for the flexibility to explore crazier research. I think this argument is bullshit and demonstrably false but there are influential people that advocate for it.
