The responses below are kind of funny. The government already runs key infrastructure. I'm not sure if the argument is government vs. Corp. Frankly governments are more likely to consider public interest than corps are. That's not to say that they always do, but corps almost never do. This is why government sells things like spectrum or land for railways if they don't own the rail themselves. They also own things like roads. It's important to realise that there is no incorruptible institution in the world. Maybe domain name management is actually a great use case for blockchain or some other truly democratic distributed accounting/ledger system.
