Here's the thing about a store of value... 

you eventually have to SELL at least some of it, otherwise you're not STORING it, you're DISPOSING of it. You're locking it up and then throwing away the key.

The question is 
  how much to sell, 
  when to sell, and 
  for what purpose.

And that's an individual value judgement. 

 Yea, I agree, people must use bitcoin for what ever they want and like. Some for long term use like a house and short term gratification. Others will see it just as assurance. Only the person with the bitcoin decide what is the right of using it. Bitcoin don´t care how you use it.
