For now, I simply trade them on an exchange an convert it to fiat. But trust me, maybe in 10 years time, they'll be more use case for bitcoin. BTW, there are online stores that actually accept bitcoin as a means of payment (
see here). So you don't really have to make use of it in a physical store. However, it's only a matter of time.
You are right and i believe that by the way we will be able to spend bitcoin to buy our daily stuffs but im not really sure if this can happened all over the world...as you now there is many countries where governements dont care about bitcoin at all
