Airgun vs Firearm

I want to make sure I am getting into high end airguns for the right reasons.
Here is how I currently look at things – please tell me if I’m missing the point at all. I realize it is pointless to try and make a definitive list like this, its just my thoughts and nothing else.

Airgun pros:

• not a firearm
• lower cost per shot once initial investment is made
• advancing the technology
• relatively silent
• bragging rights – I did it with an airgun
• accuracy
• more easily self sustainable
• easier to tinker with
• they are just cool

Airgun cons:

• Lower shot count at higher calibers
• Generally single shot at higher calibers
• lower range
• generally requires longer barrels to achieve power needed

Firearm pros:

• consistency
• no need to refill anything – load and go
• generally more power and precision in smaller packages
• more options

Firearm cons:

• its a firearm
• regulations
• loud
• ammo availability and cost per shot

I think if I were to summarize all that – For me, the #1 reason I dont enjoy shooting as much as I should is because by nature I am frugal. I look at every shot as money out of my pocket.
The noise reduction, helping advance the technology, tinkering, are all secondary to that for me.

Am I getting into this sport for the right reasons?
