If we had a near-perfect hydrogen -> helium fusion engine, why would we want to stop at 2,000 saturn V rockets of mass? Hydrogen is cheap AF.

Also why would we only want to stop at helium, why not fuse any further?

Also why would you want to stop at 1g acceleration - why not 1.5g or 2g, say? Surely living in 2g environment is okay for that period?

However presumably there is no good reason for us to go there. Just because there are planets doesn't make it worth the trip.
