I suppose the idea would be that if you are selling a good or service that isn't actually worth much, then the companies that don't buy will have an advantage over those who do, and eventually it should be self-correcting, if only because people tend to imitate the winners. This wouldn't make all B2B entrepeneurship sensible, but it would not have a tendency to get worse over time. Whereas, in theory, rent-seeking via government has no such reason it would not get ever-worse, as attempts by one company to influence government result in competing companies doing the same at first as a defensive measure, and then while they're in the lobbying game why not try to get something for themselves as well.
