I was playing months before I was age verified. With AEGs etc. While it's true you can not access the AV area of the site without it this place is not the be-all end-all of airsoft.
What may help is finding more "storefront" style of bricks and mortar locations. You may live in Bugtussle but chances are good a few times a year you will travel to a less remote city. Meeting a private person in a city you're not familiar with on a short time line can be a headache. If you had a solid 6 days a week 9-5 location to drop in at then that would help quite a bit.
Airsoft, where nothing is hurt but feelings.
