I'll add my $0.02.

I store up to 40 gals of gas (increasing to 50 gals) and I add 2oz of Stabil for each 5gal can. I keep all of my fuel in a tin shed (store bought, assembled from a kit) that doesn't have any electrical power.

I'm storing sufficient gas to run my generator for 80 hrs (5 gals = 8 hrs running time) or to provide 1 refill for each of my vehicles (van req's 30 gals & the truck req's 20 gals) which would allow me to make it to my mountainous deep shelter and friends.

1) Is your garage attached to your home?
2) Do you have a gas or electric hot water heater and/or clothes dryer?

IMO, a "yes" answer to either one of those questions spells a very large, nasty, explosion in your future.

IMO, explosive mixtures (such as gas) should be stored away from the house within a ventilated structure that has no electrical or natural/propane gas service/appliances.

IMO, storing gas as an inflation hedge is not worth the risk for the small amount of fuel that you/we are discussing. Storing that amount of gas as part of a Bug-In or Bug-Out Plan makes sense, particularly if you balance the amount of fuel on hand against the known or perceived threat for your location and time of the year.

I reduce my gas storage during the months of Dec - May; increase my stocks from Jun - Dec. This provides the highest level of preparation for hurricane season while minimizing my "risk factors" during those time that I don't actually have a need for that larger amount of fuel.

I currently have 30 gals stored and will hit the 40 gal mark when I go home towards the end of the month. I'll hit my max amount of 50 gals just before the height of the hurricane season.
On Dec 1st, I'll pour my oldest 10 - 20 gals into my vehicles (Merry Christmas). I'll deplete another 10 gals in January, etc, etc. In May, I'll buy 10 more gals, another 10 - 20 gals in Jun, etc, etc.
