Beyond the ethnic cleansing issues everyone already presented:

• How are you calculating the ‘value of the land’?
• Who deternimes the value and where the new borders are to be drawn?
• Do family estates get prorated for sentimental and historical value?
• What is the conversion rate of coastline and maritime claims to arable land?
• Does Israel get to keep the value of settlements that it already holds either “legally” (per Israeli law) or illegally?
• Why would Israeli settlers in illegal settlements vacate, and (perhaps more to the point) why would the Israeli state stop backing them when they decided not to leave?
• Why would Egypt give up control of an excellent defensive border region to a hostile neighbor for a noncontiguous state that would likely be re-occupied by said state before the treaty ink is dry?
