Respectfully, this is one of the many starry-eyed "we seek to achieve the impossible" posts in these comments that refuses to address the practical realities. You're not going to erase radiation exposure with a motivational speech.
Radiation exposure will be easily survivable in the short term. Astronauts have already lived in space for longer than a Mars flight, and Mars explorers will have, at a minimum, highly shielded sleep areas during the trip. With a VR setup, spending a lot of time there might not be too bad...
Spaceflight oriented radiation shielding will also improve over time.
On Mars, radiation won't be much of a concern at all, since all living quarters will be underground, either under piled regolith, or deeper underground.

it's physically impossible with current technology for humans to survive a trip to Mars and live on the surface
space really, really wants to kill life
cosmic rays will kill humans before they even make it to Mars
there is no current technology that shields from cosmic rays
we should appreciate the earth greatly for its atmosphere and magnetosphere that shields us from them
best emulation idea so far is to surround astronauts with several feet of water
but we don't have the lift capacity for that much water weight
the total time on the moon outside the capsule per person maximum was 22 hours
the astronauts kept seeing bursts of light even with their eyes closed
when NASA inspected the helmets there were microscopic groove where some had made it all the way through
cosmic rays are physical particles traveling near the speed of light
the bursts of light were their nerves and other cells being destroyed by the cosmic rays
it was happening to their brains and CNS too
mice exposed to simulated cosmic rays became slow and stupid

You seem to say this as if it’s some sort of enlightened reason to “not”
Instead, I suspect for many, enumerating, quantifying and solving the impossible is precisely the reason we venture into the unknown.

We call moon shots “moon shots” because we landed on the moon and generated incredible generational wealth from the technology in the process.
Had we not, we would call moon shots something else.
