Of course not, that is just a transaction in Bitcoin.
PoW mining on the other hand, by nature will transfer value out of an eco-system. They use hash rate to process transactions, and obtain transaction fee (and possibly
new coins), then they sell these back to the eco-system. So basically, the eco-system is paying a fee for them to process transactions, and also possibly create new coins.
Then the miners use these fee to buy hardware, pay electricity bill, pay pool fee etc... These are money permanently transferred out of the eco-system.
What if they sell to the 'new' people (outside the "eco-system" whatever that is)? Or if they sell to existing bitcoinholders who then sell back 'outside'? Why did you assume that entire $500m is paid by eco-system? That would only be true assuming that bitcoin doesn't expand at all.
