This kind of thinking can be used to invalidate any hobby that you're not personally into. I used to think like this and honestly I was a major asshole because of it.

"People travelling is just attention seeking, going to places where millions have already gone just to get a few pictures while emitting a bizarre amount of CO2. "

"Festivals? Why travel all that way and cause all the noise pollution (and pollution in general) just to see some dude press play on a CDJ and listen to mediocre quality music that you could just listen to at home. "

"Board games? Why waste all those resources and all that money on something that could just be a computer program? Save the money and give it to poor people instead."

"Fashion? Biggest nonsense there is. Just make clothes that fit well and are durable. We can just stop this pretentious rat race and save a lot of resources. Would also help with body positivity if the examples we see aren't over edited photos of anorexic models with otherwise perfect features in ridiculously expensive clothes."

And I could keep going. You can reduce anything people care about to a waste of time, money, and resources that could be spent elsewhere. We're not on this planet to be the most efficient and selfless versions of ourselves, we're allowed to just enjoy things even if they seem a bit wasteful and ridiculous to others. That doesn't mean that we should never think about the impact on the environment and other people when we do something, but it's a balance. And just because we don't like doesn't mean that it can't be important to someone else.

I'm sure that to some people their Christmas decorations are the biggest happening of their year. They'll think of what to do the entire year and nothing in the world will fill them with more bliss than seeing their house decorated the way they envisioned it.
