That is because it will instantly lose any right to access sovereign Israeli horbors of airports to ship goods and out, will instantly lose access to Israeli-controlled crossings to Jordan as a hostile nation, Israel keeping the Jordan Valley as a security belt to block arms smuggling, and will instantly lose any right of transit across and on Israeli roads to its annexed blocs of Jewish towns. So no worries about taxes on imported goods of selling anything outside of the PLO-Hamas state - beacause noneof this can happen without violating Israeli sovereignty. And don't have to worry about shipping goods to anywhere for income, because without Israeli-supplied fuel, electricity and water from Israel, no goods will be produced. Price of continued access to sovereign Israeli access - 1) recognition of Israel as Jewish state, 2) outlawing of Hamas and dismantling and disarming it, 3) return of Shalit, 4) unconditional negotiations on borders and peace treaty - and forget any "swaps" for what Israel keeps, that is the penalty for unilateral "declaration" - all past deals are off. No international law anywhere can force sovereign Israel to allow anybody to use its land or resources - just like Arab oil embargo on Israel, Israel will embargo all outside contact and supply with the "independent state". Meanwhile, Gazastan's continued war-like conduct will result in a far more restrictive Israeli clampdown on access, as an enemy "independent state" that has declared war on Israel by claiming the right to destroy it- not "occupied", as international law". permits.
