The POW fork of ethereum after merge is basically a made up "money", or am I wrong

So we've seen all over the place that there will be a ETH fork which keeps proof of work concept, after merge is finalized.

Does that mean if I have xx number of ETH on current chain, I will also have xx number of ETH on the forked chain?

So how is that not a creation of "money" out of basically nothing? Assuming of course that the forked chain gains(keeps) the traction from current miners and becomes listed on some exchanges so it could be traded(which will happen in my opinion since a lot of $$people would have big intetest in it).

Current miners just continue staking their aquired ETH and continue supporting the existing network, and instead of selling their mining equipment they shift to supporting the fork.

Double profit out of thin air on the expense of suckers?
