Basically what I want to say is Bitcoin should be spent where there is a Proof of Work to produce the good or deliver the service.
For example a surgery, the doctor is not doing any other thing but the surgery, coding, the engineer is not doing any other thing but coding, honey, the bees spend all their time producing honey...
However a coke is just a matter of putting more capital to produce more cans, a car, same thing, a lightbulb...
Happy to read your thoughts...
