1. What you said, when we normalize logic, is: videogames are just as useless as bitcoin. If videogames disappeared, humanity would be allright. Same goes for bitcoin.

I wonder if that is exactly waht you were going for.

2. Videogames are not useless. You could start with the fundamental need of humanity for games in general. Yes, if videogames disappeared, we would find other things to replace them with. I wonder if someone would then pop up and say something inane like "BTC is not an ecological disaster - just like Gaelic football [1] is not an ecological disaster."

Secondly, videogames are increasingly found to reduce stress. They are used to treat various patients [2]. They broach the subjects such as "games as new medium" and "games as art". They create vast online communities.

Bitcoin (and blockchains in general) laboriously appends entries to an append-only log using the power-equivalent of several countries at a speed of a paraplegic snail [3]. And in ten years it hasn't found a single niche where the same operations can't be done faster and more efficiently (and are usually already done faster and more efficiently).

[3] All-time high for bitcoin was 450k transactions per day: https://www.blockchain.com/charts/n-transactions To do this, it requires more power than most countries in the world: https://www.visualcapitalist.com/visualizing-the-power-consu...

Since we're speaking about videogames, in 2006 Eve Online had 150 million DB transactions per day. To do that, Eve Online needs something like 6 database servers: https://www.eveonline.com/news/view/tranquility-tech-3

Bitcoin would need the heat death of the universe to handle a comparable load.
