How would a libertarian society function?

Hi all! I’m not a libertarian but I’m exploring the idea after I saw some interesting statistics, I had a few questions I’d like to ask about libertarianism if you all don’t mind;

How will infrastructure (roads, aqua ducts etc) be built?

How will things like corruption inside a corporation be stopped (like if a CEO embezzles money)

How will environmental damages be protected against? (If an oil company spill water in a gulf)

Will stocks be a thing? How will they function and be regulated?

Who gets punished for what (if I rob who arrests me)

Are things like slavery going to be acceptable?

That’s all (I think?) Thank you!
