After I expatriated some years back, I began to sever most all of my links with the USA.
With the exception of family (which are very strong links!) and friends, I have now done so. Of course, I've also set down roots in my new home offshore in the Caribbean region.
Severing links has its advantages. I'm much less likely to be sued where I now live and do business than I would be in the USA. And I don't spend enough time there to become subject to tax other than U.S.-source income.
Probably what I miss the most, though, is the "convenience culture." Being able to order something online and to receive it in two or three days is a rare luxury here in the Caribbean. Many companies don't ship abroad for various reasons, among them a fear of running afoul of U.S. export regulations. Not to mention the mountains of paperwork required for exports.
The best solution I've found for this problem is to use a U.S. remailing service. International remailing services in Houston and Miami and other major cities will provide a U.S. address to receive your shipments and letters. The remailer will then forward them to you in the islands.
While these services are expensive, the advantages are compelling. You have a U.S. address, and therefore don't trigger the "we don't ship to foreign addresses" rule of some companies. You also avoid the "we don't want to deal with customers outside the USA, due to the compliance procedures" that some banks whine about.
While I shop online for items I can't obtain locally, these companies provide the service I need to actually receive those items, albeit at a higher price. I consider it part of the price to pay to be a free, sovereign individual.
