Yes. Smithing and Enchanting makes the game far too easy. I liked a few of my playthroughs where I completely ignored Smithing and Enchanting. If I want to use one, I only use one not both, and I don't powerlevel it.
Or you can use them both to bring sub-par armor and weapons up to a useable level. For instance, I like the look of Leather armor, so I can get a very high Smithing score, Enchant some smithing gear, buy a 50% smithing potion from an Alchemist, and get my Leather armor to the armor cap! Some people like to wear Forsworn armor, etc. It is overpowered if you are trying to make the best possible gear. But it comes in handy if you just want to RolePlay with looks that aren't as good stats-wise.
