There is a difference though. People, who produce art or any other kind of entertainment of thought provoking things, mostly at least partially do it to add something to society, or to make us think. Putting money into energy intensive speculation, which does have no real world value behind it is not in the same league as those activities and is definitely not productive. Even counter-productive, as it is using up energy, which could be used for useful things. At the end as in any such speculative endavour, one person's gain is another person's loss, no matter how many abstraction layers and smoke screens are put up.
