I don't think you're looking holistically at the environment of building a dynamic website with no experience at all programming, which is what I think this conversation is about.
If you can, put aside all that you know about language design, frameworks, and software engineering, and try to think from the perspective of a person just wanting to "get something up". Say you want an online store. An online store requires a shopping cart. You ask google how to do this, and google tells you: How to build a shopping cart with PHP. For whatever reason, php was chosen by the internet gods to be the beneficiary of a positive feedback loop: beginners use php, find it easy to use, write tutorials. Tutorials attract google, which means the community is likely to be less of the programmer type (programmers would already know how to do these things in python) and more of hobbyists/internet entreprenuers with little technical skill. Because this community is comprised of less technical people, they are more understanding of the shortcomings of n00bs. They turn away less "stupid" questions, write more tutorials and abstract more of the academic attributes of programming that "make it work". By virtue of attracting so many people, inevitably, there will be some truly capable practitioners that will go on to have success. Derek Sivers of CD Baby fame is one I can think of.
The point i'm really trying to drive home is that the accessibility of a language isn't just about being easy to learn, but about having a welcoming community and environment that helps new users.
