It's not assumed, that's the objective of state: To create a sustainable and consumer-oriented market through regulation and incentives.
This is again, a feelings-based assumption. States do not behave according to this goal.

What feelings are you talking about?
It's not a feelings based assumption, it's the role of liberal democratic states determined by the basic principles of democracy. That the states do not fulfill their role is their own fault.
And capital has a tendency to kill off competition you assume will just appear and magically take over.
