Is this blown out of proportion or a real problem ?
It is a real problem.

I read the Wikipedia article on space dust a while ago.
This might be a different question from moon dust, however
it might be that the moon dust could be the partial result
of dust impacts on the moon, or at least it might be
theoretically possible.
It seems to me that about mach 25 or low earth orbit is
a lot 'faster than a speeding bullet'. So if you have a
particle of dust or even sand hitting you at mach 25 that
could in theory have some effects - the particle of sand
may be small with a small amount of mass, but it could be
hitting you at high speed because of the comparative speeds
and directions of different objects in the solar system.
It also said that some of the effects of impacts with
space dust could be similar to that of sand blasting in
some ways.
Nonetheless, there is also such a thing as the 'solar wind'
and that is 'gas' dispersed throughout space in the solar system.
That though very small to likely close to hard vacuum could
form a drag against objects at high speeds like rapid
'dust'. Is there a minimum size and maximum speed of dust
particles in orbit in the solar system, before the dust interacts
with the gas of the solar wind and gets carried out of the solar
system? What sort of problems have happened from collisions with
rapid 'space dust' in the past?
