Given how much of the total weight of a rocket is required for fuel, 5% is massive.

  I mean its a big deal on a statistical level for many launches adding up, but it’s not exactly going to take us somewhere we can’t otherwise go.

    It kinda does, a bit. "5%" by itself is a little vague thanks to the rocket equation relating delta-v and payload fraction with an exponential.

    It does for rockets with many stages, as the lower stages will get an exponential benefit.
