Bevel set. Yes. If you have a bevel, you should be able to shave. It will be a scratchy shave and I doubt you'll want to leave the edge like that but it should remove hair. Tape. Its not a cheat or a crutch. Think of it as a correction. Whatever you have to accomplish without it you still need to do with it. If you don't cut that bevel, tape or no tape, you won't be able to shave. But if you've ground away enough steel to rightfully expect a good bevel and the edge isn't holding, tape can correct that by adjusting your angle. There's no point in using it unnecessarily, but if/when you do know that its not a cheat.
