The reason so much disruption comes from "barely skirting the law" is because government sets up the law/regulation to entrench these old business models.

This regulation inhibits growth and promotes stagnation, evidenced by the fact that NYC cabs did not accept credit cards until 2007 and by how obviously under-served the SF cab market was.
