Oh, it's not a question of laziness; I could simply leave saving enabled at any point on the map, but I think that would worsen the experience.
I think limiting the number of save points and adding a narrative sense to the background of the story and the character as ‘safe’ places for him can create a sense of tension and unease and make the player act more carefully.
In my game, you never die suddenly unless the player makes VERY BAD decisions, so they always know when they are at their limit and need to find its "save place" 😁
