While I do agree for other reasons, the problem you state can be solved by being paid with bitcoin. Some employers (notably, police) do have the option to pay wages in bitcoin. Though these are very few they are still there.
Not necessarily that all employees will adopt with bitcoin that is not relevant if they are not interested on bitcoin. Most just like to directly receive their paycheck and spend right away, bitcoin will not give them convenience because they are not into it unlike us who considers bitcoin already as part of our life. In the future when bitcoin will be majorly adopted, investors, traders, gamblers, and shoppers online will most likely be benefited.
If we talk for nowadays then you are true not much people will want to get it and fiat will survive as it is and will be regulated as even well educated people do not know about bitcoin while in the future when it will be announced on media channels then people will learn about bitcoin and will then like to adopt it when they will hear about it.
