If this were true, stars couldn't form from hydrogen clouds. The primordial universe had only hydrogen. Fusion in stars created neutrons and helium, but this only happened as a result of high temperatures and pressures caused by gravity compressing hydrogen until fusion starts. So I don't see how a universe where protons didn't create gravity could develop stars.
