So, VTVL RLV without a parachute can control a landing position, need same, or less additional weight (and less aditional details), and need same langing construction as the your scheme.
parachute landing == you have no control of a landing point.
Plus for "using rocket on last metters for prevert dammages" you need same additional landing construction on LV (launch vehicle), as in case of VTVL (Vertical takeoff, vertical landing).
In any case, you need not more then 10% mass fuel (from returning weight) to landing RLV (reusable launch vehicle) by VTVL scheme. And - now Falcon use some additional fuel mass as "ballast mass".
A parachute masses more than all the fuel that has to be burned to do what's shown in the video? If that's the case then yeah, the long burn is a better way to go. It just seems strange.
"+ Plus the inevitable damage during parachute landing."
I was assuming that you WOULD use the rockets for the last ten to a hundred metres.
@BringBack500s I read that it is because of the labor. It's basically a shuttle and a rocket together. The Space Shuttle may end up as the most inefficient and expensive spacecraft in history.
@matthewakian2 600mil for a shuttle launch, apparently a saturn5 popped 115 tons into leo at 1/3rd the cost 35 years ago. Something does not add up...
Such a simple and ingenious idea. The real question is why where Nasa not doing things like this decades ago? I couldn't believe it when I heard that every space shuttle flight cost more than 600 million dollars.
@SailorBarsoom Yep ) I hope too).

A parachute wiegh == 1/10 from a returned mass weight (much more for wings).
+ Plus the inevitable damage during parachute landing.
VTVL much more good.

A nice way to not leave our shit in space, but it adds more fuel to be reusable.
