There's no point discussing Mars colonies before we can even have long duration habitat.

If you are too full of yourself to recognize space make thermal regulation easier than a hell varying between −17.2°C and −107°C there's no reason to answer you.

No one said the giant cylinder would come before the infrastructure. Don't confuse me with the martian who believe they'll 3D print their "new world" infrastructure from a few hundred BFR landed on Mars. The main difference is that I don't pretend a thousant people in thin can are colony until we've perfected self-sufficient space-habitat. Point at which scaling up is just a matter of economic efficiency and exploiting asteroids is a requirement

Say the guy who believe he won't need a small nation worth of industries and farm to expand his pod-camp on Mars.
The O'neill cyclinder you seem to imagine is the biggest thing you could make using TODAY materials with 30% margin (it's not even carbon nanotube). It's essentially suspension bridge technology and heavy lifting which we will need anyway.
Since it require self-sufficient colony in SPACE (of any size) before landing on Mars, all you've been saying is that you'll send a bunch of people dependent on space welfare, claiming to be a colony until they are sent an industrialized country in kit, or a magical 3D printer to do so.
I simply don't believe in your gravity hole frontier and build the industry in orbit, exploiting the moon, asteroid and still colonizing space.

No doubt but if you have that technology there, then you'll have it in space long before.

Which is why the industries want to bring the asteroid/resources to the station instead of the reverse. It's only the Pioneer dude who can't imagine people being anywhere but the surface of Mars.

>large scale asteroid mining for OTHER reasons
Whatever your other reason are, it will be before any mars colony.

It restrict severely the design with somewhat aerodynamic cargo spaceship, even using ballute.

Rigid capsules or inflatable ones?
Methods of radiation shielding?
Aboveground, or underground?
How many launches, using SLS vs. Falcon Heavy?

I know there's some design genius to be had on /sci/.
