thanks, for my campaigns, my players either use resources or die, I am stingy with rests so potions are the only way to heal in some cases. I give out plenty and they are encouraged to use them. I have noticed in the official materials that "potion of healing" is the most common magic item found for treasure, so someone creating this content expected those potions to be given out freely. I explain it to my players like, imagine potions of healing are like finding a soda beverage in a post apocalyptic world, you would definitely drink it.
