I have a different reason why the conclusion doesn't follow: while it's true that less populous states have outsized influence in the senate, the constitution doesn't require (and in fact, originally discourages) the federal government to engage in the kind of activities being discussed here. These activities should be the domain of the states. But a long history of expanding federal power (and various supreme court decisions affirming those expansions along, in my opinion, dubious interpretations of both the constitution and various statutes, especially the commerce clause) has led to this issue.

The fact that North Dakota has a lot more influence in the US Senate than California on a per capita basis shouldn't be that big of a deal, because the US Senate should be doing a whole heck of a lot less than it is, and states should be picking up that slack.

The more power and responsibility we have given the federal government, the more the issues appear....because it's doing things never intended or envisioned by the founders.
