I think my comments regarding Price of Smiles really got lost in the weeds - my point wasn't really the tractor specifically, but the lack of cost associated with Yuki Soleil's decision in general. After all the people who've paid a hefty price to carry the story thus far, & after we're cautioned by everyone how potentially damaging & disasterous her decision would be, it just.....wasn't. It's incongruent with the established tone of the series & is logically inconsistent.
Okay. I see what you're getting at. However, I would posit that it wasn't as drastic as it might seem due to the nature of their power sources. The impression I got was that the 'free energy' was actually killing the processes that made life possible on the planet. So, while they were losing out on free electricity, plants were able to grow in abundance again. So, it was kind of a trade-off.
But, beyond that, I agree that there should have been a year, at least, of absolute devastation and hardship. The problem we're looking at here is the show is trying to appeal to a particular crowd, but expose them to a different theme not normally found in the kind of show they watch, and still have a happy, feel-good ending. So, they gloss some things over. I could tell from the start that this show wasn't meant to be gritty realistic, though they try to tackle 'War is Bad', simply due to the nature of the lead characters in the first ep, and the fact that there was a narrator to explain things. So, I knew, in spite of the general theme, to expect something of a light tone.
I'm not trying to defend their decision. In fact, I feel a lot of shows have been getting an overcorrection from the morbid horror style skull-****** endings of the 80s and 90s, giving a bit of a too-positive aspect to the hero-team dynamic, which is taking away from what could be if the story was a little more level-headed/handed. That Time I Got Reincarnated as a Slime is another show that, though I enjoyed it, came away a little too easy for the protagonist. But, like Knights and Magic, I take it for what it is.
