There are psychology of purchases, you forget the fact that Bitcoin being adopted in globally can enable consumer to have a borderless transactions, which can promote purchases. People will always buy what they wanted and desires.
Bitcoin blockchain provides borderless transactions since its create in January 2009.
It's only matter of people that they accept this blockchain and bitcoin for their trades or not. If they (two sides of a trade as trade partners) accept bitcoin, they can do it smoothly because Bitcoin miners simply confirm transactions from tip of mempool to maximize their transaction fee and income from mining. Miners don't care where these trades are made and between what trade partners and entities.
