'... you need some way to regulate chain tension.' ... don't guarantee chain tension ...

regulate =/= guarantee
The issue isn't whether you can guarantee some amount of tension in vertical drops - of course you can. The issue is whether you can adjust it, which you do with horizontal or diagonal drops by moving the wheel forward or backwards.
