Or I can just open up a tiny hole in the shield temporarily to allow a single freighter to past through and supply fuel. I don't have to lower the entire shield. Plus the stations also have small stockpile.

And the frieghter can be destroyed in transit and that small hole can be fired through...

Can I remind you that a snall hole in this context is several hundred meters wide?
