Well if you would stop building strawmen maybe it wouldn't be an issue.So, we are now adding magical greenhouses made by retired wizards on top of the special magical plants made by archdruids and the interference of the gods.
All to prevent halflings from trading, like every other race.
Do people still not understand why I am so frustrated with this conversation? It seems that people's natural response to halflings maybe having to deal with the outside world is "throw more nice things at them, make them more comfortable, protect them"

A village might have a magic greenhouse because such things exist in mods. They do have interaction with the outside world, they just aren't particularly interested in trade because they're happy with what they have. They don't have to "hide" their orchards doing more than not having them out in an open field. They don't have to have spices to survive, but they would be happy to use them if they did.
None of these are issues unless you make them. It's not like they're a real race, nor has someone written a PHD thesis on halfling culture.
