I find this thought pattern to be helpful because the state has all the government powers not given to the federal government, and not found to be contrary to the constitution. The tenth amendment guarantees this - "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
Each state, as a small nation, has its own interests that need preserving outside those of the United States at large, and it makes sense that the senate acts as a check on the interests of large, populous states over smaller ones when it comes to these.
Having lived in several states, I've found that differences in values and culture inform general opinion of the federal government. In my opinion, this article sounds like it was written by someone who views the United States federal government as one that should have a large role in the every day lives of citizens, and my feedback to them is that they should consider whether or not they would like it if a growing state with different values than their own suddenly had disproportionate representation federally.
