Well, healing by spells is FAR cheaper than healing by items. You get 1 HP per Gil with an item (except with Tent, which gives even less, and Elixir which depends on your Max HP), while the Cure spells give 25 HP per Gil it costs to restore the MA. Even with the Elixir you need a max HP of more than 37,500 to be able to get that kind of cost efficiency, and I'm not sure that's even remotely possible. And for comparison, the healing center is 5 HP per Gil, which is also far better than items.

But.. there is still the problem that I would need to cast even the best healing spell 3 times to fully heal my HP atm, and I can't even use it yet (it's level 30).
