BP, Greenspan was an avid follower of Randism & convinced the likes of Clinton that with less regulation, market forces would ultimately be self correcting to create a balance. The lack of regulation as well as the non enforcement of regulatory controls were some of the main drivers of the GFC. Even Greenspan now admits he got that wrong. One of ACT's major pieces of policy is a to reduce regulation.
Luckily the ACT party isn't a political force so we don't really need to be concerned what there policies are or how naïve they are either.
