Your reasoning is interesting, but can hardly agree with them. So, you are arguing that the most important basic characteristic of materials is "uniqueness" or "non-reproducibility." People and all living objects in general, in order to ensure their continued existence, must leave offspring, that is, constantly reproduce. Then, according to your theory, we have no signs of materiality. And bitcoin, which is just a mathematical algorithm, has become tangible.
To have materiality, any object must exist in time and space. If the object is not characterized by them, it cannot be recognized as material.

I think your this sentence is very reasonable.To have materiality, any object must exist in time and space. If the object is not characterized by them, it cannot be recognized as material.In the bitcoin network system, we have seen an independent time system, which is separated from the time calculation of our physical world. It is completely independent of bitcoin itself. This is the timestamp server of bitcoin. It constructs an independent time system, not relying on any external system. We determine the causality of one thing's sequence according to the block height of bitcoin. However, when it comes to how bitcoin builds an independent space system, to be honest, I don't have a clear answer now. I'm still thinking and exploring.
