I agree with you on the problem you raise, but not on the solution. Bitcoin as a store of value is a temporary madness which cannot last forever. The reason which makes this madness "normal" is that the mainstream finance has become even more mad and even more disconnected from reality. Therefore Bitcoin is a sort of "lesser madness" compared with the fantasyland of mainstream finance. Both of them cannot last forever. It is not clear which would collapse first though. As for the solution you propose, making more Bitcoins is not necessary, since there are more an more new altcoins which cover the function of "more bitcoins", supplying more assets that can be used as a store of value.
