Its not so easy to stop BTC transactions. There are a lot of forms to make BTC transactions... you could do it with SMS, with GIFS with ofuscated data, via phone, via mail, via twitter...
But yes, as celticninja says..." If you are not on the network you cannot make transactions on the Blockchain."
and what is if you live in el salvador and got payed in BTC? or if you travel from europe and change your EURO for DOLLARS...if you enter in a shop and pay with dollars you are countertrading in euros?
