Are we approaching a time when the "Default Theme" is the only one available for WordPress?

Themes are built by (mostly) creative people. They offer the user a choice in how they want their website pages and posts to look. Why then would we want to limit what that user can do because a software default two levels up is take it or leave it? Do painting artists have a restriction on how many elements they are allowed on their canvass?

Having too many unchangeable default settings simply stifles the creativity of the theme developer, and thus, the user. And limiting that creativity may one day cause many websites to have the same "look" – much more than some do today.
