Seems like you quite confident. So go on. Expand on that a bit... its trivial after all.
You will teleport all that mass to ELO? Or use tracker beam to capture asteroid and space mine it to smelt shielding.
I am super curious how you solve it trivially.
edit: You downvote but dont explain this trivial solution. Am I asking too much? Calling someone out to explain something is offensive or something?
Folks on Mars is still quite a ways away. Not impossible or pointless by any means but it will require significant advancements in many domains before we can really do it safely.
As an aside, this is why the original Moon missions used simple aluminum. One of the typical angles people who don't think we landed on the Moon used is that to safely get through the Van Allen Belts we would have needed massive lead shielding on the craft, when in reality it was shielded by a pretty thin layer of aluminum, precisely to minimize secondary radiation. If you put that thick lead shielding on the craft that people intuitively think you'd need, it very well could have killed the astronauts.
And every ton you take increases fuel cost.
Currently you need what 10-20 trips to fuel for moon. How many trips would you need to fuel trip to mars? You would need a fucking conveyor belt of starship to prep the mission. Who is going to pay for it? And why?
Just because the materials for shielding/tools are simple it doesnt make the solution simple.
On the water topic, here's [2] a very readable little writeup on the mass inputs required for longterm space missions. Water makes up the overwhelming majority of your requirements. Starship, in its current form, can carry 150 tons. And that will be substantially increased once the tech is stabilized. A sizable chunk of that storage, for Mars missions, will be water. Also, the big threat is not the persistent ambient radiation, but infrequent extremely high energy bursts from solar weather.

Mars has essentially infinite CO2 and hydrogen. So this means we can produce essentially infinite methane and water. In fact you can carry out electrolysis on some of the produced hydrogen and feed it back into the system. This leaves you with a final excess product of methane, oxygen, and water. The Starship's engines, uncoincidentally, run on oxygen + methane. So we can locally produce basically limitless amounts of water, oxygen, and rocket fuel on Mars.
Of course this begs the question of what we do initially. And like all long distance colonization efforts, you're not sending just a single ship, but rather a small group. Those other ships are carrying additional critical supplies, including fuel. Upon landing those ships can also be used as shelters until something more permanent can be constructed. And the extra fuel provides a means of getting back to Earth if necessary while giving you a big window of time to start establishing basic local infrastructure including energy and methane production.
The permanent dwellings and really whole infrastructure would be underground. Lack of atmo and magnetic field basically forces you to dig down. Limited resources - rudimentary food and water. More less bunker life
On top of that 0% prospect of return. Essentially you are doomed to penal colony for the rest of your life.
I find it hard to believe anyone would want to sign up to that. And the people who would are absolutely people who should not be sent there.
And what happens if earth decides supporting mars outpost is pointless, you want alex jones types create conspiracies that colony is fake and its a tax payer scam? What would that do to minds of those stuck on mars?
And the Mars program is not being publicly funded in any way, shape, or fashion. If it was - we would have likely colonized Mars decades ago. Werner von Braun - the man responsible for the success of the Apollo program already had workably viable plans drawn up for Mars before we even set foot on the Moon. The government's decision to defacto cancel the space program is what led to his very premature retirement. But I do think rapidly aiming for the basics of self sustainability will be important nonetheless. Fortunately Mars is almost set up like a video game in that most of everything we need to survive is somewhat serendipitously present.

As for what people want to do. It's funny, because I feel the exact opposite. I simply cannot understand people who have no desire to adventurize, explore, and see all that this universe has to offer in what little time we have on this Earth. It's probably why I'm an American yet find myself living half way around the world. And I would be the first to sign up for a mission to Mars as well. It'd certainly be a rather difficult life, but what more could be more desirable than spending the rest of your years laying the foundation for our children and our childrens' children, so that one day people coming to Mars would simply be just a holiday. And perhaps they then will then be the ones laying the foundation on Europa, or perhaps destinations that we can't even realistically imagine today.
It's certainly the same mindset people leaving the luxuries of the Old World had when setting out for the New World. The Old World was richly developed and full of culture, life, and civilization. Going to the New World entailed a voyage, as long as 4 months, and one which was quite frequently deadly. All to get to a completely undeveloped chunk of land full of oft unfriendly natives, new diseases, and all sorts of great ways to die in the middle of nowhere. And that's if you survived the voyage across to begin with, which many didn't. In many ways, we have it easier.

Yes, it's more, but it's really not _that_ big of an engineering stretch.
