This can work, but properly shutting down not only is for syncing the filesystem but it properly terminates applications. I.e. editors might remind you to save changed files or the desktop environment could store its state. Away from desktops some server applications can be graceful (I.e. instead of terminating a HTTP request while processing active requests could be finished, but new requests by the load balancer be rejected, databases can clean their state etc.)
