The comment I was responding to was a fair question. I didn't mean to imply otherwise.
That said, your comment contains several significant misconceptions, and you are far too confident despite not having any idea what you are talking about.
First, neither elevation.fandom.com nor Wikipedia are good sources for Jewish thought. How things seem to someone who has no background knowledge after consulting a poor source is of little interest to anyone engaging in serious consideration.
Second, as with most questions in Judaism, there are multiple opinions. Most communities eventually agreed on one position to follow (at least in practice). In this particular case most communities settled on the more lenient position, but just as often it settles on more stringent interpretations. That has no relevance to the question of whether or not Eruvin are a loophole.
Third, Eruvin are not a loophole. They are not an escape hatch or an attempt to weasel out of the rules. They are an elegant extension of the rules that simultaneously uphold the letter and the spirit of the law in the face of changing circumstance. If you understand this it is obvious why we cannot have a single worldwide Eruv. Because it breaks both. It also just straight up doesn't make any sense.
