(I'm assuming you meant "travel and spend", rather than "order for shipment", since the latter is handled by applying sales taxes to imported goods.)
First, if they're traveling that often, they're going to be paying a substantial amount of travel expenses, subject to sales tax. Might also be worth considering if currency conversions should be subject to sales tax.
Second, who can afford to do the majority of their spending in another country, while not actually being a resident of that country instead?
Third, a country would get significant additional tax revenue from visitors and tourists, who don't make income in that country but do spend money in that country.
Fourth, where's the money coming from? The business they derive their income from has to pay sales taxes too.
And finally, a vanishingly small fraction of people could actually do that, and it's not worth making the tax code a hundred times more complicated to target a tiny number of people who will still end up paying a huge amount of tax in other ways. The administration alone isn't worth the additional revenue; you'd spend more administrating the more complex tax code for everyone than you'd have any hope of recouping.
