Came here to post this ^
Another issue is that coomers, similar to alcoholics, will use masturbation as a self-reward for doing ordinary things.
"I'll wash the dishes and reward myself with a beer" "I did 20 push-ups, I'll reward myself by cooming" etc;
This makes breaking the addiction to pornography and masturbation even more difficult because no only are people dopamine fried, they've also conditioned their behavior around their vice which can make it hard to suggest things to distract away from the urges to engage in the behavior. I know personally lmao, because when I have to do any cleaning I say to myself "alright I'll clean for 30 minutes then go have a cigarette" to give myself something to look forward to while doing boring stuff I don't like to do; but it really is imperative to, at the same time a person is detoxing from dopamine to start instilling other habits and other hobbies and other activities otherwise they'll end up relapsing when they get to the end of the tunnel and realize they have nothing to do anymore.
In my opinion. Video games are not a hobby. They're a fun activity, but they're not something people should associate as actual hobbies; however... making video games is definitely something that could be considered a hobby. It's just my opinion but a hobby is something that we engage in for fun, that we end up with something at the end of a project. Sitting down for 2 hours to play a video game generally doesn't accomplish anything; and I think while trying to kick a bad habit it's important to see real life results and be able to hold something in your hands and say "whoa, this thing didn't exist yesterday and now it does because I made it exist"; it'll give you something to focus to distract from the withdrawal, and it'll give you something tangible that proves that your efforts in doing something will be rewarded.
That's just my two cents on the matter though.
Not every hobby has to be expensive. I like making self-enclosed ecosystems with stuff I find on nature hikes.

It costs basically a mason jar, which are like 2 bucks. It gets you outside, it gets you out in nature, you get to learn about different plants, mosses, bugs/insects, etc and it's fun to put them together and build a little mini world for any of the bugs you bring home. Isopods, beetles, snails, maybe a spider or a centipede or two.
If you do it right they'll last years.
That's just a suggestion though, there are plenty of other hobbies that cost next to no money
