They just need to spin, and voila! gravity (sort of).
And the dynamic stresses on the outer ring of a wheel-type will be HUGE. You could brace it ten ways from Sunday and I wouldn't get on it. A spinning barrel would require many times the amount of material.

I'm not an engineer, but I did hang out with them when I was at Purdue. And I was an engineer in the Navy for twenty years.

And one terrorist with a bee-bee gun, and instant people sucked out into space.

With regard to the lack of a magnetic field, I posted earlier in this thread about a theoretical way to provide Mars with one without re-melting the core.

It's mega-engineering, but it's theoretically possible within this century.

If a magnetosphere could be provided for Mars, I'll enthusiastically allow for an atmosphere.  I have my doubts though.  But I never claim that problems can't be overcome.  "Someday", we might land on the small liquid metallic surface of Jupiter.  But I want to see HOW first.

I am reminded of a supervisor who used to ask "can a computer do that".  Well probably, eventually.  How much funding and how much time is the question.  Who knows WHAT we can do given money, interest, and time?

That is what all irresponsible governments and plutocrats say.  Money is no object.

Every project manager knows there are 3 parts  to any task (Omnes tres projects habere partes, as Iulius might have not said).   Funding, time and quality.  You can set any 2 but not all 3 at once.  Managers are idiots who think that all 3 can be defined by fiat.

Why terraform another planet when we could just terraform Earth? I think Neil De Grasse Tyson said that.

We should do both. All our eggs in one basket, a recipe for extinction.

So? Why does anyone care if we go extinct? The universe will be just fine if we're no longer existent.
