1. you cant take Apple shares into an Apple store declaring you already own the products to just take them away.
you cant take Apple patent for a certain chip into an Apple store declaring you own the products to just take them away.
2. bitcoin is an asset.
this is because just like a patent, share, brand its not tangeable(physical object) but intellectual ownership.
to say bitcoin is nothing is the same as saying brands, patents, shares are nothing.
3. the OP can make the same argument that fiat is nothing. that people need to convert products/services into value measured in fiat for fiat to have value.
bitcoin is the same it has an actual cost to its creation and people use it for products and services and vice versa
the argument can be expanded into anything tangeable(physical) and non tangeable(not physical). take cow manure. many think that it has no value and is nothing. yet if a farmer wants to give it utility by using it as fertiliser. then it gains utility which gives it value.
unlike 99.9% of PoS coins that have no coin creation costs and no infrustructure to sustain utility. bitcoin has both cost of creation and utility.
4. here is an argument that the OP should consider and understand and agree with
its all about cost of creation, utility.
this is why its important that bitcoin remains a medium of exchange. as oppose to just becoming a store of value for the sake of only being a store of value. as that would then make bitcoin worth nothing.
without a medium of exchange, miners wont want to use their costs to create it to then find they cant use it.
people wont want to buy it if they cant use it for anything
thus the cost of creation depletes as miners withdraw. as the utility will be gone that gives it some of its value in the first place. so thinking of bitcoin as becoming just a "store of value" without utility. will be a downfall of bitcoin.
but to suggest bitcoin is nothing. is to ignore its cost of creation and its medium of exchange currently
I don't understand what are you trying to prove. Apple shares represent the ownership of something (multinational technology company). Fiat currencies also represent the ownership of something(debt certificates). Bitcoin is a system for digit manipulation, and as such it has nothing to do with ownership, i.e. by owning the result of digit manipulation you own nothing.
