What if the population decreases rapidly in the future, while Monero will keep churning out new coins in eternity?
Don't you think the deflationary nature of BTC will shine for a store of value?
Store of what value ? what value does it have if it's not used for anything aside from speculation ?
If population decreased drastically (I suppose WW3 or Alien attack), then the crypto they hold would most probably disappear with them.
We need new supply to replenish the lost coins.
