Gliding figures are a complete introduction
Quickstep without jumping is not a makeshift substitute for the real dance. Its repertoire of figures includes movements that do not require an airborne phase. In a beginner course, these figures form the foundation of the lessons: you learn to combine steps of different durations while moving with your dance partner. A quarter turn or a gliding chassé does not need an extra hop to serve its purpose.
For a complete introduction, what matters is that your steps fit together, not that your feet leave the floor at the same time. The fast music already demands your attention. The short steps need to land at the right time while you stay connected as a couple. Jumps would add another task that simply isn't necessary.
There is no general requirement to perform jumping figures at a ball, either. A manageable gliding repertoire can be enough for an entire dance, as long as you can repeat it confidently and adapt it to the space available. Connections matter more than constantly learning new individual figures. You'll encounter this principle when connecting Foxtrott figures, too, even though the specific transitions are different in Quickstep.
