Why would an Israeli live next to the Gaza border?

Cheap housing and free vacations.

Is an evacuation consider a forced vacation?

The reason housing is so affordable is that homebuilders in agricultural communities located within 7 kilometers of the Gaza border get their land for free. In addition, they are eligible for a 100,000 shekel ($27,500) government rebate on their building expenses. Many agricultural communities in the region also offer new families the option of renting for five years and using the money spent on rent toward the purchase of the homes should they choose to stay on. In this way, they avoid having to make a down payment.
Special tax incentives also apply to the Gaza border communities and, among other perks, residents are eligible for free organized group vacations once a year, paid for by the government.

Doesn’t the IDF use those settlements as an excuse to annex more territory from the goyim?
