There is an energy cost to take the fuel up in the air just to use it to
get back down.

You can't use parachutes on something that large and traveling that
fast. Rockets would be a lot easier if you could. It was somewhat
successful with the spaceshuttle but they basically had to rebuild
them anyways after they scooped them out of the ocean. They were also
much smaller and solid boosters. The cost of the fuel is nothing
compared to the cost of the rocket.

Parachutes large enough to slow the speed down sufficiently, and
landing legs robust enough to handle a 2 meter/second landing would
probably be heavier and cause more drag than keeping some residual
fuel for the powered landing.

Seems like that's a waste of fuel when you can use parachutes.

Pretty cool. Launched, delivered goods to orbit. Landed
first stage vertically back at the launch site.
First time ever for that complete chain of events.
Too bad it was a night launch. The landing video is not very
good.
