BTC isnt money tho ^^ its a store of value.

You're acting like bitcoin has a finite supply.  In theory it does, but not in practice since transaction fees are recycled and mining continues FOREVER.  It's the equivalent of if platinum costs $1000 an ounce to mine at some point but people are recycling old cars and getting it for $100 an ounce.  The lowest available price is the only one that matters.  It doesn't matter if the cost of production was $1 million for a coin at some point. It's an open entropy system so if the cost of production goes to zero, people simply plug into the system and mine those recycled coins for free rather than paying you $1 million.  

If there are no recycled fees to mine, it means the system was already dead in the first place.  The act of making fees recycle is the equivalent of infinite supply, just with the store of value aspect of that supply resting on cost of production instead of scarcity.  Each halving doubles cost of production, which enables you to increase price or lower mining input.  If you run out of halvings and then lower cost of production, you should have a corresponding effect to devalue other already existing coins.  Do you see now why cost of production actually does matter?
