This is pedantry. It's the same as them saying "You need a rocket to send a payload into space" and someone retorts "No: you can also use a space elevator". The presently is implicit, and space elevators don't (yet) exist.

The initial statement is saying that there is no physical way to achieve this feat today without lidar. While millions of agents (humans) are currently doing this today without lidar, or even eyes in the back of their head. I don't see anybody/anything with the blasé regularity of human drivers without lidar (machine or not) moving things into space except via space craft. So to boldy claim that lidar is NEEDED is absurd. Speaking of getting things to space, I remember people telling the same guy, Elon, that you NEEDED a new rocket to launch your payload into space every time. It is funny, you needed that until you didn't. All the while, humans we, with the blasé regularity of human drivers without lidar, not throwing away their cargo aircraft every time freighted between airport.

Keep the "pedantry" name calling out of this.
