You’re not wrong, but even later Souls games do a much better job of explaining to players their mechanics than early Souls games. Having the blacksmith right in your hub area and having the player encounter upgraded equipment early on really helps tell the player “hey, upgrading your equipment is important.”
There’s still a bit of that in other games, but consider how the first chest you find in Dark Souls 3 (is a mimic, but) has an infused weapon in it, and in the very next area, you’ll find an infused and upgraded shield. Or the way that the lack of weapons to be found in Bloodborne encourages you to focus on one in particular, and so you’re more encouraged to invest in upgrading that weapon. It helps that they did away with the complicated systems of Demon’s Souls and Dark Souls in 2, 3, and Bloodborne, even if I did think the system of “evolving” your weapon was neat.
