Thank you for your thoughtful comment!

I always thought of relational databases as a tool for businesses; normally we don't need them as individuals--except perhaps when planning a wedding! Thus the pricing is targeted for businesses and people who get reimbursed by their employers. A second group might be contractors who purchase their own tools.

There might be ways to make a separate tier for private or occasional use, though. And recurring vs. perpetual might be a separate question from the actual total expected cost.
