> bed frames and box springs are mostly superfluous and a mattress on the ground is more comfortable and cheaper
I was also of this persuasion and did this for many years and for me the main issue was drafts close to the floor.
The key reason I believe though is mattresses can absorb damp so you wana keep that air gap there to lessen this effect and provide ventilation.
> getting up from a squat should not be difficult
Not much use if you’re elderly or infirm.
Other cons: close to the ground so close to dirt and easy access for pests. You also don’t get that extra bit of air gap insulation offered by the extra 6 inches of space and whatever you’ve stashed under there.
Other pros: extra bit of storage space. Easy to roll out to a seated position if you’re feeling tired or unwell
It’s good to talk to people about your crazy ideas and get some sun and air on that head cannon LOL
Futon’s are designed specifically for use case you have described so best to use one of those rather than a mattress which is going to absorb damp from the floor.

I was concerned about this as well, but it hasn't been an issue with us for years. I definitely think this must be climate-dependent.
Regardless, I appreciate you taking the argument seriously and discussing pros and cons.
A major con of bedframes is annoying squeaks. Joints bear a lot of load and there usually isn't diagonal bracing to speak of, so they get noisy after almost no time at all. Fasteners loosen or wear the frame materials. I have yet to find one that stays quiet more than a few months or a year without retightening things; but I haven't tried a full platform construction with continuous walls which I expect might work better, but also sounds annoyingly expensive and heavy.
