Firstly, there's no reason the trip can't be one-way, or at least, temporarily one-way.
Secondly, there's not a huge need to develop a new rocket. We've delivered lots of one-way cargo to Mars using the Atlas V; something like the SLS could deliver much more, plenty for a couple humans to get there and not die. We've already launched SLS uncrewed around the moon, there's no reason to think it would take decades of dedication to launch one again 1-way to Mars.
From there, step up to the ISS, which costs about $4B/year to maintain and operate, an order of magnitude more.
It's likely another order of magnitude (tens of billions/year) and probably more like two (hundreds of billions/year) to do the same thing on Mars.

Though, to be fair, there are a lot of other things we could spend 10% of the USA defence budget on that would benefit humanity a lot more in the short term.
Sending a live human, or group of humans, on a suicide mission in the name of bragging rights as a species would be really bleak. I doubt you'd get much political support for a Mars mission without a return plan, or at least a sustainability plan.
Don’t take this as support of mars colonoziation which I think is a fools errand. Just pointing out that “suicide mission” seems to actually be motivational to the intrepid adventurer.
Edit: I suppose I should have said "a few humans [permanently settled] on mars, [able to return whenever they like]" in 100 years.
It'd also be cool to send an empty rocket with auto-landing capabilities and supplies way before the manned mission, and when those Mars visitors arrive, they can move the tech needed for survival (which would've been invented/improved in-between) to the return rocket.
But that all sounds like Kerbal scenarios rather than real life ones.
This is the ultimate admission that it can't be done. Anyone sane would at least propose a free-return trajectory like Artemis 2. Even if you are crazy enough to sacrifice your astronauts on a one way trip, you would still need to practice a lot of free-return trajectories just to train your astronauts and test the hardware.
This whole idea is the stupidest thing I've heard people seriously discuss.
What would be the point?
If you want to experience "life on Mars", bury a cargo container in your back yard, and live in it for a year.
If there's some burning need to go live underground, as you would on Mars, why not just do it in Nevada? The grocery store is a lot closer.
The post at the top of this thread is correct in saying the logistics of supporting a colony on Mars would take decades, and cost billions (at least).
I'm an advocate of exploration and science, and in the modern world we have effective automation. There is NO need to send people to Mars, absolutely not in any large number.

If the crew includes elon, I am actually in favor of this...
Can you write this with a straight face? This feels like the opportunity of a life time for someone who wants to push the envelope on what is possible. Yes it will be expensive, but the tech and lessons we learn will surely be worth more. Consider all the developments from the Apollo program. This level of pessimism always shocks me, shouldn’t we rise to the challenge?
A rover runs mostly on solar power. Humans need breathable air, food, potable water, medical supplies, stable temperatures, radiation shielding, etc etc just to survive, let alone actually do anything. Unlike sunshine, Mars has none of those things. And if any of them fail, your human rover would quickly go kaput.
It seems far more reasonable to use automation to build a livable outpost before sending a human there - especially because a human is going to need that outpost to survive anyway. So even if we want to send people to Mars eventually, automation would be step one.
- Portugal, 1490
the Ottomans had cut them off following the Fall of Constantinople in 1453 (or where they didn't they taxed the hell out of them).
they knew for sure there was good stuff over there, and just wanted a new way there.
we know for sure that Mars is blasted, toxic, rock ball with less metal than Earth. what great and grand spices will future explorers be returning with? the Portuguese could prove that nutmeg and silk existed...
