Yeah, and if you're lucky enough to find a seller that way, 9 times out of 10 it will be a wholesaler who will only sell you stuff if you have a corporate account, meaning you either own a business yourself or are cleared by your boss to purchase stuff.
Add to that the ludicrous shipping costs for anything weighing more than a box of cereal, insane import duties for anything worth more than say $50, plus a fat VAT slapped on top of all that, and most people in the rest of the world* will probably think twice about it.
TL;DR buying enterprise grade gear of any substance from across the globe as a consumer is a little bit more involved than ordering a pair of slippers frome some seller on AliExpress.
