you are wrong, again...
you dont have any possibility to avoid that people buy from another country. you just can make it harder for them by the two ways i described above.
its like following:
ship comes to Antwerp unloading goods produced in a foreign country, a trader is aboard and offers it to marketeers in your country, he has his money before you can do anything and your people can buy from the marketeer.
now, at the same time you decide to buy from the ship either, you put it in your depot and from there it is distributed to traders in your country.
however, if people already bought the same good, they do not again.
What can you do?
either make the customers loving you, make them loyal. this is represented by the technologies more or less.
OR, make it extraordinary expensive for foreigners to sell in your country. set high tariffs.
now the people have to pay the price plus the tariff and its more expensive than your own goods/goods in store, people buy from you to save money.
the trader however will not accept to pay the tariff from his own purse, he will sell elsewhere for the normal price.
so, techs and tariffs make it possible to have a higher rate of sells from own production or stocks in F4....
just go to Hessenhuis
