Air exchange rate: DIN 4108-2 requires an air exchange rate of 0.5/h. You can argue about whether this number makes sense or not, but how one is supposed to achieve this with manual ventilation under realistic conditions in an airtight building is a mystery to me. I am not saying that it is mandatory to build with controlled residential ventilation, but when I compare the air quality in houses with and without controlled residential ventilation... huge difference. But of course, like with most things, if you have never gotten used to the better condition, it’s not so bad or rather doesn’t matter.
As my previous posters have already said: always having windows open is unacceptable to me, keyword noise protection, energy, and burglary. The comfort argument, however, is the stronger one for me. Waking up in the morning, even in winter, and having nice fresh air. No discussions with children about ventilating, windows mostly closed due to increased burglary protection, etc.
Regarding the special waste issue: This concerns WDVS of the older type with a certain fire protection agent (HBCD). First, this no longer applies to the current ones (as it is banned), and second, it is such a politically important topic that a solution is being found for the earlier WDVS as well (the first federal states have already found pragmatic short-term solutions... disposal therefore possible).
If you generally have something against materials derived from oil, you will probably have to do without quite a lot. Car with plastic fittings? Couch in the living room? Synthetic components in clothing? Yogurt in a cup? Do you use a toothbrush (I hope)? ....
Algae: This is not a phenomenon limited to WDVS, but you also see it on houses without... You don’t have to have biocides in the exterior plaster either....
