Replying to Having avalanche gear when nobody else does

When out on season I ski a lot of off piste with friends without any safety equipment.
Fortunately I've never been involved in any avalanche but last season two Danish skiers were killed in an avalanche within days of me skiing the same run which shook me up a little.
Now I'm interested in buying some avi gear but I've only ever met one seasonaire with an avalanche transceiver, shovel and probe.
My question is, what would be the point in buying my own avalanche gear if nobody else has it? Would an airbag be a better option? What are your thoughts?
