We can and NASA have recently created oxygen on Mars.

I’d imagine it costs more than a plant does. In addition, plants pick up carbon dioxide from the atmosphere, which isn’t necessarily replicated with every oxygen producing technique.

Might be more complex effects we rely on plants for, I’ll let smarter posters fill in the gaps.

We can, people have already done it. It’s just that plants are a *hell* of a lot better at it than machines are (or likely can ever be), so we may as well just keep the plants around, or replace them. It’ll be a lot cheaper and a lot nicer to look at.

Why would you need to automate a process that nature already does on its own, unattended and on 100% solar power?

we can force plants to grow faster in high CO2 greenhouses with artificial grow lights 24/7, but then you need to power the lights, concrentrate co2, which need electricity, and no matter how large your greenhouse it will never be close to the size of all the forests on earth

we can but its expensive as shit.

even if you would be able to do it youd basically have chlorophyll floating around in a synthetic cell, youll also have to add enzymes to maintain the chlorophyll and chloroplasts, and to create more enzymes youll have to add a ribosome and other little organelles.

you created a plant cell, just use a plant cell

Because doing was would be extremely expensive, probably not worth it (produce more greenhouse gases than we could get rid of once the process has been made useful), and living in a glass, steel and concrete hellscape is not really an appealing reality for most of us.
