Profit maximization is one goal among market participants, though not the only one, since the market also encompasses modes of organization embarked on for communal and personal reasons as well.

Profits are a motivation to act, but they may be nonpecuniary and psychic. Nor is "earning money" the ultimate goal in any sense, insofar as holding nominal money balances as a store of value becomes intractable with greater capacity. Now, subpar monetary and financial arrangements may distort savings-investment decisions, but this is not an intrinsic market deficiency.

Regretting your decisions ex ante is inherent to humanity, not to economic systems.

Regulation is and has emerged endogenously. Guilds, unions, standards agencies and other quality assurance bodies arise without state action.
