The resources needed to transport stuff are not free, and they usually involve petrol instead of legs.

It is not that easy. One delivery truck delivering to multiple people can be more efficient over them driving individually.

A warehouse can be more efficiently cooled and enlighted than a shop for individuals.

A big kitchen preparing menu after menu can be more efficient than heating up the oven for a single use. A restaurant using larger supply packs can be more efficient than household sizes in packaging and transport.

It's a case by case thing, but average for a few domains might not be that bad.

Cooking meals at home probably takes fewer resources and creates less waste overall.

However, assuming that there's driving involved in either case, I wouldn't think having an order delivered from a big facility is much different from you going to a restaurant and picking up takeout.

Because I can literally never leave my house for anything at this point even late night booze and there is something eerie about that.

There is a certain "The Machine Stops" [1] sense to it. I have mixed feelings. I can get very little rapid delivery where I live. Sometimes, I wish I could just order some takeout, but it's not necessarily a bad thing that I get forced to either go out myself or make a meal at home.
