Can you imagine how many shipping containers it would take to feed 1 billion mouths even for a week!?
When your colony first establishes the Pop is basically brand new and has to grow, it's only a few thousand people really.Even if I can't imagine, I put that 1 billion people on a ship in the middle of no where for 20 years and they didn't die of starvation.....so I assume any kind of physical constraints are not a concern.
The POP is not counted.So each pop represent one billion ? damn those guys breed like bacterias.
But they don't represent 1 billion. They represent what you want them to. For example I had an old birds game, to me they represented a few million per pop as they were slow breeders and that's how I RPed it. No where have the devs ever said (that I've seen at least) what size a pop is.It's an intentional design decision.
There is no universe in which it is cost effective to resolve a food shortage equivalent to 1 billion people worth of consumption by shipping from somewhere else. (Each -1 food of shortage represents roughly enough for 1 billion people.)
If your planet has a shortage you need to upgrade or build more food structures.

It's certainly possible to move food from orbit down to the planet, because of the Orbital Hydroponics Farm starport module, so in theory, you could have ships bringing food to the starport, to distribute onto the planet. (I'm not sure on the mechanics of moving stuff down to the planet - is there a space elevator ? or surface-to-orbit shuttles ?)
However, consider the size of ships needed, the number of ships needed, and the frequency. Those cargo ships aren't free.
Say a ship can carry 3 food. You'd need 12 of them arriving each year, to supply food for 3 pops. What's the maintenance cost of those ships ? They'd have to be very much cheaper than a planetary hydroponics dome, in order to make sense ingame.
It would alter space strategy, by providing something to attack and defend, which might be interesting for some players. But the management of it would be a bit fiddly, I think ?
Guys, it's a game mechanic by design. It matters not if it is or isn't feasible.

It means you don't snowball out of control (especially over the AI) with one massive food producing colony which ships food to all your other colonies. Thus Colonisation is still an investment due to the time it takes pops to grow.
