Obviously forces of nature go from strong to weak with scale, and there is probably one that is even weaker than gravity holding galaxies together. Surprised this perplexes people.
'I just made up some random loose assertions that I am taking to be self evident so that I can feel smug about them'
There is a reason intuition is insufficient at these scales - it's extremely frequently wrong. Your navel gazing is worth only the lint you find.
Just hand waving a suppose force isn't going to satisfy anybody in this domain, you've got to back it up with some math at least before anybody cares.
