Think there is a difference in your example
the in laws are not people living in Gaza. They can go in and out of Gaza
people living in Gaza can’t that easily leave the area. They need permits which many times will be refused.
this is from 2017 so not sure whether it’s outdated tho I guess not by much
For the last 25 years, Israel has imposed increasingly strict restrictions on travel to and from the Gaza Strip. Those restrictions affect nearly every aspect of life in Gaza, including the ability of human rights workers to document violations of human rights and international humanitarian law (IHL) and to advocate for their remediation. While Israel makes exceptions to its travel ban for what it calls humanitarian reasons, as a rule, it does not permit Palestinian, Israeli and foreign staff of human rights organizations to enter or leave Gaza
. It also severely restricts all travel between Gaza and the West Bank, recognized as a single territorial unit, even when the transit does not take place via Israeli territory.
First, it says, travel between Gaza and Israel inherently endangers Israeli security, whether the travelers are Palestinians or not, and irrespective of any individualized risk assessment for a particular person. Second, it says, its obligations toward Gaza are limited to allowing passage for exceptional humanitarian circumstances only, and job-related travel for human rights workers does not qualify as exceptionally humanitarian.

uman Rights Watch said today on the fifteenth anniversary of the 2007 closure. The closure has devastated the economy in Gaza, contributed to fragmentation of the Palestinian people, and forms part of Israeli authorities’ crimes against humanity of apartheid and persecution against millions of Palestinians.
Israel’s closure policy blocks most Gaza residents from going to the West Bank, preventing professionals, artists, athletes, students, and others from pursuing opportunities within Palestine and from traveling abroad via Israel, restricting their rights to work and an education

Contrary to popular opinion, Israel did not begin restricting movement between Gaza and the West Bank when Hamas seized control of the Gaza Strip, but rather many years earlier. Today, out of millions of Palestinians, only a few thousand people are able to travel between Gaza and the West Bank each month.
