Why pay for blog hosting or software?

I’m not quite sure why people would opt to pay for blog software like MovableType or TypePad. My guess is that paid blogging companies have a hook into their current user base and people continue to pay each month. But why?

Lets start with TypePad. TypePad starts at $4.95 a month and increases to 14.95 a month. For the basic package, you get one user, one blog, no access to the blog template, no money making ads (for you), no domain name, no real ownership. You’re just renting so you just get the basics. 100Mb of space 2GB of bandwidth is pretty good for a blog but not worth paying for. The Pro account gets more features, transfer and space, but is it worth the price?
