Wood in today's society needs chemical treatment or physical isolation before we use it a construction material.

Only because we use a lot of pine wood with low density (because cheap&fast). Not all wood is like that: Red cedar, douglas, larch, acacia and more... Where I live, chestnut is even used for roof tiling.

And then there is cork

Indeed... still used for wine bottles. I can't say I'm too happy with it though, given the amount of bottles spoiled by bad cork.

The screw top for wine bottles, one of the best inventions in recent decades.

Yes... easy to open, easy to close, needs no tool, preserves the wine. No drawbacks, unless you're into nostalgia.

I've started seeing screw-tops as an accessibility feature after the last time I got a bottle with a cork that was impossible for my mother to open and ended up crumbling anyway. I'm done with corks forever; they just don't make sense.

Wood is useless for sterile applications because it harbors bacteria and such. Think dentist, doctor, chemistry labs, industrial processes, food manufacturing and packaging, chemical storage, etc etc. All Plastic.
