I don't think it's particularly disrespectful, isn't all that's needed a change of perspective? What makes it disrespectful, precisely?
The common method of embalming in North America seems more disrespectful - pumping a body full of chemicals that weren't there in the first place and helping to pollute the earth.
Composting seems like a mixture between cremation and natural burial. At the funeral ceremony, the deceased disappears into a machine, as with cremation, but eventually the body will feed the soil, like with natural burial.
I think it's mostly a slower, cleaner version of cremation, though.
Those strawberries were your aunt before she was born. Did you know strawberries and other foods go into producing humans? And when we die we, if given a natural death, we can go into producing foods again? It's always been that way. If you want to make the argument that @spinach's view is poisoned by futurism, you ought to take a look at yours which I'd argue is poisoned by modernity. You are the earth, you are of this earth and you'll go back into this earth eventually unless you opt for some expensive astro-death where you'll eventually land into some other material planet into that dirt. And shared memories are immaterial, detached from that person once they die. That's the beauty of those memories, that's what makes them special, the fleeting moments in the nows and thens knowing none of this will last forever. I get that it may make you nauseous as it does me to some extent but OP's view is far from "fucked up".
It's all cultural though. Other people with other culture would find disrespectful that you don't dig up your dead once a year to wash them up and give them new clothes.
