Let's not argue.

I am looking at some random blocks. What I see is that a single transactions is a
hash -> Don't know how to compress

Impossible without losing data.

index -> why not sort by time, input etc, something 'drawn' from the data?

What index and what sorting are you taking about?

We have inputs and outputs. For example, frequently we have inputs from the same origin, why not add them up for storage?

What do you mean add them up? New transactions need to be able to reference the inputs so simply "adding them up" won't allow clients to create transactions.

Just looking at a set of blocks make we wonder why we can't map them in a way that we just cut of all the leading zeros. ++

That could be possible but how much space will that really save?
