Thank you Fyron & geoschmo
So, to restate what you have said, in another way:
1) A blockaded planet is prevented from contributing to the empires global pool of minerals, organics, radioactives, research points and intel points.
2) Otherwise, a blockaded planet will function normally except for:
a) its inability to contribute to the empires global pool and
b) the effect the blockading enemy ships will have on the blockaded planet's happiness.
Edit: And whether or not the planet has the only space port in the system is irrelevant.
