you can create any number of Bitcoin clones and they are just as good as original Bitcoin.
Yes, but any of the clones will not have the same trust and good publicity as the original one.
Less trust = less value.
What your saying is very similiar to "
What would happen if i mixed some chemicals (or manipulated matter at subatomic level) and produced something that looks, smells like gold and has every other property of gold".
Nothing special would happen. Depending of how scarce is the thing you are producing, and how easy is it to produce more, it would have bigger or smaller value. The harder is to produce a thing = the more scarce that thing is == the more value the thing has. Also if it is easy to divise, shape and carry, then it can be used as a currency. This rule works with everything.
