OK, that's different from saying magic *can't* do something.
Also, there can be a certain prestige factor in doing things the hard way.
People still buy hand crafted items, even though objectively mass production could make make them a lot cheaper.
People often prefer natural flavours even though the synthetic ones involve the exact same chemicals.
People could prefer magic in some situations for similar reasons.
Same as I prefer real books to digital ones, and records and LP's rather than CD's.
