But you can create an arbitrarily high number of bitcoin-like electronic currency units, simply by taking the exact bitcoin implementation and changing the genesis block
Yes, you can. If your X-coins will be in some respect better than the original ones they may even supplant bitcoins. But you'll have to put of effect in order to convince people to use them. With uncertain results. Currently bitcoin has network effects working for bitcoin and against other crypthographic/p2p currencies. To change that will require a major effort.
The history of bimetallism (gold & silver) is relevant in this respect. The final result is that your are better using the medium of exchange the majority using, so usually there only one money left.
