On that context, "stack" means exactly the set of all those things and a few more. You can't replace it by any one of those things. The alternative is enumerating all of them (that's what people used to do), what is bad (that's why people coined the "stack" term).

> anti pattern → bad design

Hum... Now are you talking about software architecture, UI, UX, communications design? Your replacement is confusing.

> key value store → (almost always) database

It is an specific kind of database, with performance characteristics that are completely different from the relational databases that the "database" word alone implies.
