how would the network work after triple halving?

So a lot of ppl are saying that eth will be cut in half three times after the merge and that we will become a deflationary coin, the price should go up and so on.

How are we going to be able to use Ethereum Blockchain if there is so little in the market and everything on price will sky rocket?

Are we expecting that price will skyrocket to 10k and we will be paying $50bucks just for a quick transfer and a mint will cost thousands even thou the gas is at 50gwei?

Thanks for explaining.
