Large rockets still help, even if shielding is not straightforward though.

  Certainly. And if we had a big enough rocket, we could put its fins on earth and the tip on Mars and just climb up the middle.

    That all skips the interesting middle values of the problem parameters :) . Seriously, for long time already it's not a rocket science. Existing technologies - with engineering efforts - are capable to bring humans to any point between Mercury and asteroids. We'll likely develop something better, and Solar system would be all reachable without major breakthroughs. Certainly not of the kind "rocket fins on Earth, tip on Mars".

  Shielding ESPECIALLY is straightforward, though. The parent was wrong about it being hard.
