Disable moving using titlebar

[codd]

I can move a window by dragging its titlebar. Can I disable this capability? I'd like to get habit of moving using Alt key + dragging. For example, once I removed maximize and minimize buttons, I got quickly used to Alt+F9/F10.

Why not install a minimalist Emerald theme that simply doesn't include a title bar? If you're trying to look really hardcore or something, you could also just kill gtk-window-decorator. = )
