Why not in Europe?

It's very rare, but you can probably find at least one store somewhere in Holland that sells them.

The reason her PVs/MVs are not aired a lot outside asia is because Ayumi, or any other Japanese artist, is not very well known outside Japan/some parts of Asia.

avex trax (the recording label she is signed to) is very careful with their money and they do not dare promoting their artists abroad, they don't even send their artists for tours through the rest of Asia. Japan is a huge market, huge enough, the second largest after USA, I believe they are pretty satisfied.

So... the main reason why Ayumi Hamasaki is not broadcasted madly on TV outside Japan is that she is very unknown in the rest of the world, she might seem pretty popular having a huge forum like this, but no, in general no-one know who "Ayumi Hamasaki" is.
