I have the same problem. Tools follow me home all the time. Being a single guy really amplifies this as well. From what I see on this forum there is no cure it only gets worse.
I have been thru most of this. If I wasn't in biz I wouldn't have it all. Its one thing to get what you need but to be a compulsive collector isn't worth it. Buying a reasonable air comp is a good investment for a young guy, good to get some basics out of the way where you "can do" something because the utility is in place, you can always buy another took quick, often pay for it with first use but air is like electric install.
That comp is modest, easy on the electric and will do the work and only increased time will be a little blasting, minor wait on occasion, not worth more investment for the other 99% of the time. Get a couple 1/4 t's to hard screw the fixed whips in place with a standard 25 ft hose and make each hose do as many functions as possible.
My place is industrial but I really like as few air hoses and couplers as possible, in a common garage could likely be 2, 1 on a reel and a whip along the bench. Couplers leak and unlike electric I have a habit of unhooking air tools when finished.
Park that sucker and hook it up with a couple hoses right off the bat, ball valve off the tank so you can work on system air at will, hook to hose reel and you can recover a temp hose or 2 for extensions later but would use it asap.
