Yes, the limitations are not legal requirements...
How ever, they are imposed by the manufactorer and/or importer. Meaning that if retailers do not comply to the "rules", they won't be representing that brand anymore.
Classic example of this has been La Sportiva. Generally they've been cheaper here in Yurp than in the states. Which is why (e-) retailers were not allowed to ship Sportiva-stuff to the States or Canada (agreenment was done between La Sportiva and La Sportiva N.A.)... Not sure if this is imposed anymore, but it used to be the case.
As for circumventing such mundane restrictions... There are a few parcel forwarding services operating in the US. For a fee, they'll provide a shipping address in the contintal US and then re-ship the parcel to almost where ever in the globe. I have looked into it in the past, and they seem to work well enough. But haven't actually had to resort to them, as I have asked friends in the states to do the forwarding... or I've ordered the stuff to the hotel, where I'm staying on work trips to that side of the pond.
