It doesn't for me. That is an acceptance that we are a single federal government and the states are nothing more than administrative units of that federal government. For states to remain as sovereign entities that have collectively created the federal government the entity of the state must have representation at the federal level.
As for returning back to the original state appointment of senators, that is required for the senate to appropriately represent the state government at the federal level.
The original house apportionment had representatives that had about 35000 people. The size of the house was locked at 435 in 1913. Before then the number of representatives grew slower than population but still grew. After the last 2020 census there are 761,000 people per representative. The unevenness of how many constituents a representative from Wyoming has vs a representative from California has is a point of contention in higher population states. The complaint is that the representatives from smaller states have more proportional power. I think that is a bit ridiculous but that is what some Californian's told me. Increasing the size of the house to have a more proportional representation would alleviate that point of contention between states.
Gerrymandering is a side effect of not increasing the size of the house.
