Other than cars & mobiles, I believe the rest are quite possibly negligible, maybe a few hundred million USD combined.
I don't mind banning luxury items but there should be a plan to provide local alternatives which are equally good, first for local consumption and then for exports too. Vehicle assemblers should be given 6 months to start manufacturing vehicles and exporting them, otherwise ban all Japanese vehicles and compel the local business for ToT with Chinese/Korean etc., manufacturers.
But in the immediate future, remove the subsidies on Petrol, Diesel, Gas, Electricity etc.; let the economic land mines left by Imran Khan blow and hurt PDM in the short term but when IMF program restarts and other lenders start their program (as they are all waiting for IMF) then the economic situation will start to ease, USD will gradually go down to perhaps 170-180 and that will be the time to call new elections.......max 6-10 months.
