Yes, democratized web-publishing is a great force for change, for good. That’s why I blog. That’s why I use WordPress (and a dozen other social publishing tools).
But that doesn’t mean SOPA / PIPA are a bad thing. Creative people publishing content can choose their preferred IP model. Creative musicians and artists can work outside the corporate mainstream if they want, with cheap distribution and easy access to their customer base, with a larger share of a smaller revenue stream – if they want. (That is an example of what is enabled by the democratized publishing capabilities.)
And we can all choose to ignore the offerings of mainstream publishing, not contribute to their corporate coffers. But, unless you’re a “property-is-theft” extremist, IP needs copyright protection, to the extent that its owner wants to assert that copyright (again the owner is free to choose what rights to assert, or not).
The problem as ever is potential abuse of powers of enforcement, and conspiracy theories whipped-up to focus on “censorship” and infringements against freedoms. But theft is no-one’s right. We should focus on practical implementation and safeguards against abuses, not throw out common sense.
