The idea that this is a virtue that outweighs the effective disenfranchisement of hundreds of millions of people rests on the presupposition that it is virtuous that certain states should have an outsized voice. There are two obvious problems with this.
The first is that its central claimed virtue is false in practice. It does not actually reliably give smaller states more power, as many proponents claim. Voters' voices in certain areas of Florida matter much, much more than the voice of anyone in Wyoming.
The second is that states themselves were created either 1) somewhat arbitrarily, by the happenstance of where various colonial landing parties decided to set up shop, or 2) through explicitly political processes where the states' admissions were pushed through Congress, in no small part, to help win Presidential elections.
The system was arbitrary from the outset. It has been gamed ever since.
