And with Django you often don't need to write anything.
You're right to some extent with all of your points (jinja2 is available, not default, ORM is equivalent to SQLA most but not all of the time), but they're one side of the trade-off. The other is that you're writing admin views that you likely wouldn't need to with Django.
It's not perfect for everything, but it is much faster to write with than anything else for reasons like this.
