Why can't North Korea import missiles and parts for their nuclear program through the South Korean border? I say, we must protest that. Israel is at war with the Gaza entity so they blockade it (partially, oddly enough Gaza does get a lot of supplies from Israel). To continue the analogy, just like North Korea can import through its border with China so can Gaza through its border with Egypt. As evidence of there being no effective blockade look at the amount of weaponry available to the Gaza people. Israel doesn't pretend to treat Gaza well so there's no need to whitewash that. However to some extent it's a function of Gaza's attacks on Israel. In the west bank Israel also doesn't treat the Palestinians that well and the "apartheid/occupation" argument may hold a tiny bit more water there but it's also some sort of more stable Palestinian partial autonomy over there. The west bank used to be under Jordanian control and Jordan doesn't want it back either. Anyway, as I was saying the situation is far from simple. It's not black and white.
