Pure capitalism does indeed lead to monopolies. Lobbying just facilitates monopolization even further to the extent that companies can monopolize without ever having any real value as a corporation. Google has failed at every turn with products and services, but they've held a monopoly on our data, and that's how they've maintained their grip.
