Sorry I haven't been able to watch the video you linked yet, but I thought the Wikipedia article was fascinating.

I'm curious what you mean by starship "working". They're seemingly close to booster reuse, upper stage recovery, going orbital, payload deployment, and propellant transfer. There's no fundamental reason the technology wouldn't work, right? Landing on the moon or Mars does seem like a challenge, but it's sort-of on the horizon. Return from Mars, however, now that really would be pretty crazy. Even so, doesn't this open-up new capabilities?
