Real hardware doesn't have the keyboard and mouse built in --
when you unpack the machine from the box you have to plug in
the keyboard and mouse yourself (and often you have to
buy the keyboard and mouse and monitor and maybe the
PCI video card separately).

But more seriously, the philosophy of the QEMU command line
is not "do what the user probably wants automatically". It
is "provide the user with full manual control of everything,
using a complicated but orthogonal set of options". We expect
that if users want a more "friendly" interface to setting
up VMs then they will use a "management layer" on top of
QEMU (such as libvirt).
