There's little faith that public projects have the expertise to actually get it done and make it work. It's hard for me to imagine the federal government succeeding at that for any reasonable cost, and I suppose you could blame some of that on partisan bickering. But I also can't imagine California succeeding for any reasonable cost, and it's a one-party state, so there's no excuse.
At the end of the day you need some people who actually know how to do the job rather than just argue over plans and subcontract twelve levels deep. My guess is that Birghtline found a few such people and that's their competitive advantage as a business.
