Your approach only seems to work in organisations where they are prepared to let go off the "Big Bang" release approach. In my experience, large organisations are less likely to go with your approach.
If they want a deadline, you can always count the number of cards left in the stack, and say num cards x weeks. If they're unhappy then you say: "pull out the cards you don't want delivered".

We plan for a big bang, but by having a product ready every week with the most important parts done first, then we're guaranteed to have something shippable on the big bang date. The "N cards / X cards per week = Y weeks" is perfectly reasonable. But you can also make this work with a more formal estimation process for shops like that. When I need to, I use planning poker, velocity measurements, and occasional re-estimation as part of release planning.
