You didnt own an video game cabinet in the 80s and had to pay rent so people could comple play it and put money into it so you could pay the rent for the place for the people to pay to play (an arcade)....
Continuing..
you buy/own the console, you pay for electricity/rent/mortgage, you pay for repairs, for the new/upgraded equipment, etc. So the cost is heavily externalised to the user, as a trade-off to comfort (hey you get to play from a couch/comfy chair instead of standing up).
So it depends on the usage to see if you spend less, more or break even on the costs.
I don't include cheating (i.e. after finishing D2 a few times, I started using SaveGameEditors so I can play with 'this' or 'that' set) as this has immense value that could not easily be made in an arcade.
The coins were paying for the games, the arcade rent, etc...
With home machines, you own the arcade - so you just buy the game once... dlc payments are nothing like coins for cabinets.
