As @asymptotically3 said, community banning doesn't take away your games, and in-game banning only blocks you from that specific game's multiplayer. In the past you could risk account suspension if you chargebacked purchases or redeemed stolen keys, but even that got changed years ago to just remove the specific game/license from your account instead.

Only large-scale fraud would get you banned, and even then I doubt they would disable your account entirely and not just disable future purchasing.
