Let me paraphrase your own comment in response. The issue is that the corporations, given no regulation, will start doing things like banning porn or "extreme" political views. This is not hypothetical; it has already happened on Facebook. Censorship is not purely the domain of the government. At least there are checks and balances on a government's power (as ineffectual and slow as they may be); save for the morals…
ISPs could have already tried to ban porn, but they haven't. Facebook isn't an ISP. Just because a single company has content restrictions doesn't mean every company in the world will do the same. Namecoin doesn't need DNS to bootstrap. Why would you need to download something? Do you need to download a DNS client for your grandmother? If such a system becomes adopted, OSs include it in the background, like DNS. If y…
Yes, they have. For one example when AOL was both an ISP and service provider, you bet your butt they blocked porn and objectionable speech.

I'm not sure I agree with this - the Free Basics program sure quacks like an ISP duck.

With no legal restrictions, what stops them?
> OSs include it in the background, like DNS.
I'm of the opinion that this describes a future that will never exist. Microsoft, Apple, and Linux distros have no compelling reason to include namecoin support by default, and likely never will. Especially since there is limited to no support for failover or localization of name->IP lookups. Even the lack of support for legal disputes over trademarked domains (for example, does amazon.bit actually go to the same location as Amazon.com) would scare off any for-profit company.
> Namecoin doesn't need DNS to bootstrap.
I missed that namecoin uses a number of fixed IPs as seeds for bootstrapping into the blockchain, so DNS control matters less there (well, once you have the software, that is). Of course, IPs are also distributed by a centralized authority, and routing information for IPs can be ignored by ISPs, so it's a mistake to assume the IPs will never change.
