Don't we have enough examples showing that this simply cannot work long-term, because the for-profit enterprises will _inevitably_ grow larger than the government can handle through antitrust? And once they reach that size, they become impossible to rein in. Just look at all the stupid large american corporations who can't be broken up anymore because the corporation has the lobbying power and media budget to make any attempt to enforce antitrust a carrier killer for a politician.

I think it's very myopic to say that corporate structure is the "best solution".
