Wait. I thought the planet population capacity limit would still apply no matter what, even on non terraformed worlds. Or I am misunderstanding your phrase here?
I mean, didn't we say that capacity depends on available surface? Because if it just depends on infra, I can drop one billion LG infra on ceres and have a huge population here.
I didn't express myself very well
There is a hard population cap, which applies regardless of the colony cost of the body. For non-habitable worlds, the effective population cap is either that supported by infrastructure, or the max capacity, whichever is lower.
When I wrote my original answer I had Earth-size worlds in mind and was assuming the infrastructure capacity would never reach the max pop capacity. For small bodies however, that is a real possibility.
