The opposition argument here is simply a case against natural monopolies. In many Western Liberal democracies, advances in technology have enabled natural monopolies on telecoms and public transport to be broken down. A wide range of necessary public services- such as telecoms and power generation- now function as part of a competitive market. As such, it is feasible that the state could simply deal with this problem by breaking down other natural monopolies in the same way.  Even if the state acts as a monopolist in some industries, public sector workers often have transferrable skills which mean they can move to other industries without that much trouble. For example, a public prosecutor will have acquired professional skills that enable a relatively quick transition into private or commercial civil practice.
