Just a few reflections from a new player. I want to know your opinion

I was playing skyrim for the first time, and I've been having a lot of fun with it, I haven't finished it yet but I'm already well advanced, it took me months to play because I wanted to be doing a lot of things and playing very calmly. But I ended up drawing some conclusions about the game, which I think spoil it a little.

The side quests (apart from guild quests, war, etc.) are kind of useless. You get bad items and small amount of gold, I feel like they were a waste of time, as well as the fortresses. And these quests and strongholds are in abundance, scattered around the map, I feel like they should be a big part of the game's content, but I just don't see the point in doing them. 
 Another thing that I also find funny, is the issue of money, which I think should be a challenge in the game, which would encourage you to make an effort and plan to save a lot of money, But by building your house and placing a plantation, you can simply plant ingredients and make potions that you can sell at a very high price for NPCs, practically infinite money without using a bug.I think these things are a mistake on the part of the developers, and they upset me a little, especially the issue of the side quests being useless, because I knew Skyrim as being a game with a lot of content, and I am discouraged by these quests, seeming to be a huge part of the content, simply being boring and useless.
