The voluntary confederation of the several States, including the delegation of authority to a federal government to regulate interstate commerce and to provide for taxation to promote the common welfare, is not Communism. That you suggest it is shows ignorance rather than mere foolishness.
Since you adhere to some desire to seek the collective monies from all to be doled out by some higher-up authority, that is indeed Communism espoused by Marx and his followers.
Freedom via our Constitutional process says nay to that.
Further, we do not belong to a Confederation as you state, nor we delegate all interstate commerce to a federal entity.
A lot of states engage in activities between themselves without the federal presence, just as the states of New York and New Jersey did when they constructed tunnels and bridges years ago between their two states.
To ask other states to support what benefits only these two is making a mockery of the Constitution we live under, not matter you wishing otherwise.
To take your hypothesis of 'the benefit of these two states serving the benefit of the whole' to its logical conclusion, ALL activity of any state benefits all other states, which is clearly against the Constitution we adhere to and must be a rejected notion.
It must be bliss to live under such ignorance of our laws as you apparently do.
