Not really. ('cause you can blow **** up with a gun....
)
Seriously, though.
There is always the history behind the firearm and the pride of ownership. There is the 'hunt' for a specific firearm (a poor but benign example would be collecting stamps). There are shooting matches. There's reloading and fine tuning the loads for the perfect round for the firearm. There is the challenge of learning to shoot (getting better with practice) the individual firearm. Hanging out with people of like minded interests, etc. etc. Its not only about pulling the trigger and listening to it go BOOM!
Besides, if you get bored with it...sell it. Its not unlike any hobby. Some hobbies/sports interest some people and not others.
