A proper government can never be simply a "reflection of the collective will." It must necessarily be based on an objective rule of law; not the rule of men, or 'democracy.' And the sole object of its actions should be the protection of individual rights, including property rights, from the violations that obtain from the exercise of collective will.
When a majority can vote to violate another person's rights, you have a perversion of government and the advancement of tyranny.
It is government intervention that creates lobbyists, corporatism and special interest groups who seek to petition politicians who are for sale to secure the fruits of legal plunder and power brokerage.
A government that remains within its constitutional bounds perpetrates no interference, confers no favors and invites no petition.
