1. That's not a valid analogy. The EU has no control over how people travel in other countries and any restrictions they may face. The US government does have control about how it treats people outside US borders. They're not remotely analogous.
2. The US constitution could easily be interpreted as a way that the US government should treat human beings, which means the 4th amendment describes how they should approach search and seizure of any person's property, wherever the US government has influence. Given the internet, influence now extends to computers across borders.
If you were willing to ignore English grammar and definitions, and several centuries of precedent, and many many other things, you could interpret it that way. But it would be ridiculous to do so. The Constitution is "We the people" laying down a basic framework for governing ourselves. It lays out how the government we create will act towards us. It specifically puts foreign affairs (how the government will act towards not-US people) under the jurisdiction of the President and does not extend rights to them.
This is well trodden ground. Your interpretation is facetious.
Wow, talk about being uncharitable. I'll just ignore your insult that I'm an ignoramus talking out of my ass and just address the content: the Supreme Court has ruled only twice on the interpretation of "the people", but there is still considerable debate over its true meaning [1].
The declaration of independence also makes a broad statement that all men are created equal with unalienable rights. It's not at all a stretch that the bill of rights is an enumeration of how a government should preserve some subset of those rights. This is precisely how constitutional protections have been interpreted in other countries, for instance.
> The Constitution is "We the people" laying down a basic framework for governing ourselves.
It's actually "the People" in the constitution and the declaration of independence when referring to the governed, and only "the people" in the bill of rights. Capitalization matters, particularly if we're talking about intent.
Further, the constitution lays the basic framework for establishing a government, and "governing yourselves" is only ONE purpose. Or did you forget about "provide for the common defense" aspect of government? It's in the opening paragraph of your constitution.
> This is well trodden ground. Your interpretation is facetious.
No, this is objectively not well-trodden ground, and you're kind of acting like a dick. I recommend not doing that.
