 And space is coordinate-free.
 

But real things are usually meant to consist of something.

 Which is why it's not real.

You forgot something important:
If you say ' Which is why', you need to say: why you think so.
Whitout an explanation your ' Which is why' statement is nonsense.
iow: why do you think, that 'pointlike elements' are nonsense in a smooth continuum?

 

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

This sounds strange, to say the least, but is actually quite good,
because it allows such things as 'big bang' or pair-creation.

 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.

That is similar to other professions, say medicine:

 So you want a nonprofessional to operate on you?

Science is not medicine.
It is actually possible to think about scientific problems, even if you are not a professional in that particular field, because you are not treating other humans with an operation.

I'm not a professional, but that doesn't mean, that my remedy does not
heal.

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

Well, I try to promote my own idea. That seems to be fair and legal.
You may promote your own ideas, too, even if I would disagree.
And I really hope, you like your own ideas, even if I wouldn't.
This is an important aspect of science.
