As usual you are ignoring the facts. As the link I gave said:
'On the other hand, if the gas in a cloud forms stars very quickly, so that
the particles in it are stars rather than atoms, then these stellar
"particles" do not interact strongly on short timescales (the time between
direct collisions for a star in a globular cluster is > 10^10 years) can NOT
radiate away their energy and momentum by emitting photons; they can emit
gravitational radiation, but that's not as effective For these reasons, a
spherical cluster of stars will remain spherical for very long periods of
time; much longer than the current age of the universe.'
Your constant deliberate ignorance in face of facts you choose to ignore is
very irritating. The distance between the stars in a cluster is so large
the mutual attraction is quite weak just like the mutual attraction between
our sun and its nearest neighbor. That is for clusters that are not
rotating. We have evidence that clusters can and do rotate.
