And space is coordinate-free.

But real things are usually meant to consist of something.

Which is why it's not real.

If so, we need to build particles out of these 'points', if we like to
combine GR and QM.

Fields seem to work okay.

Then we need something, that could eventually behave the way, that
particles could be a substructur under a certain perspective.

Quaternions are mathematical concepts, not real.

I wanted something different than one of the usual

'materialistic'

concepts, to which string-theory actually belongs.

We'll have to agree to disagree.  I think you like your idea too much.
