Bitcoin definitely isn't rare in kind as we've already seen how relatively "easy" it is to fork. Could just fork Bitcoin infinitely as one way to deal with its supposed scarcity.

Bitcoin isn't even rare in the abundance sense if you consider that how hard it is to mine new coins is merely a function of a mathematical curve that can be adjusted as a software change. Certainly any change to the mining difficulty and/or coin pool ceiling would be hugely controversial, but it's not like it's mathematically impossible merely politically improbable, for now.

The thing that is rare is the total amount of mining nodes behind bitcoin. That is what you are buying into, is mindshare. Of course the mining nodes are mostly profit driven. If another coin had a higher profit margin, the miners would switch over to that coin.

That rarity too is also software controlled based on the difficulty curve. Bitcoin doesn't have to boil the oceans, it could make mining easy enough again that transactions could be mined in a coffee break on an average person's smart phone's GPU.

As I said, the scarcity of Bitcoin is much more a political structure than an inherent nature of Bitcoin. The miners control Bitcoin so much as anyone does and it is their political intent as much as anything else that creates any scarcity in Bitcoin at all.

Forking bitcoin doesn't create more bitcoins. It creates something else that is not bitcoins any longer that will not be accepted anywhere.

[WorldMaker]

The philosophical and political reality of what makes a "real" Bitcoin that people can accept is outside of the question of scarcity. The fact that a Bitcoin can be endlessly "duplicated", at the whims of software developers and/or miners, regardless of how likely or improbable they may be able to be "spent" should definitely give people some pause in their Tulip mania that Bitcoins are not by their nature inherently a scarce commodity. They are scarce only so far as the political reality in which they are transacted continues to keep them scarce.

But they are in fact different. Maybe not as different as gold vs silver but similar in that gold and silver also have completely artificial values driven by hype.
