It's such a silly argument, especially if that same person is trying to preserve their purchasing power in the fiat system as is.  

 It really doesn't matter where somebody else started and where they are now. All that matters is where you are now and where you end up in the future. 

Also so many people need to understand that a fixed supply currency against an increasing population and rising productivity will keep going up and up in purchasing power.  

 EXACTLY THIS. As we properly allocate capital in a free market system, we are able to make increasing amounts of higher quality products with less effort. The money supply stays static while the supply of goods/services increases with human ingenuity. Everyone is better off. 

 less bitcoin for them, more pump for us 

 Sounds like a temporarily embarrassed satillionaire. 

 Wake your friend up.

It isn’t theft [it is…?] from a system robbing, especially the poorer— blind! 

The audacity is beyond. 

The rhetoric and lies means there is plenty of fear regarding a new system that can shatter the old. 

 Is your friend Christine Lagarde?
