Venus is in what I call the thermolocks zone, not the goldilocks zone. The thermolocks zone is optimal for solar power and perhaps therefore for computation, although heatsink radiators are essential.

The atmosphere of Venus in particular is very resource rich, and so it would be incredible to mine it for heavy use by a space economy. This mining is supposed to use free solar power. All of this is a job for robots, not humans.

Fuel for interplanetary rocket barges (coal lined tubes fed from liquid tanks oxygen), produced in the floating factories of Venus.

Sure, why not?
