Compare this to generations old server farms that require maintenance, extreme cooling solutions, run virtualisation layers on top of virtualisation layers, necessitate 5G equipment and increasingly high internet costs and middlemen, on top of a user device in the first place.

My computer can also be used as charity for Folding At Home, run my homeservers, and train my AI models. All this instead of purchasing different subscriptions for different servers. In effect, I can optimise the hardware exactly to my needs and use it efficiently to its full extent, reducing waste completely.

Not to mention game streaming will never look as good as native rendering, and "negative latency" is physically impossible. I also don't lease cars.

The latency part is true though.

>According to research, anywhere between 30 and 55 percent of a data center’s energy consumption goes into powering its cooling and ventilation systems

Meanwhile the cooling cost for a computer in a home is probably zero.

Leasing is common because people don't quite understand they're always worse off with it (though you could make the argument that it saves hassle and could therefore be worth it).

Renting is as common as it is because for a large amount of people it's literally impossible to buy a house where they'd need it (or even at all, without significant moving distance). Renting is always a terrible idea and most people understand this, they just don't have a choice.
