That's all fine and good if the democracy actually works. If it has been subverted by a corrupt elite then a desire for a real functioning liberal democracy by a vast majority of the populace can be handily written off as populism using that same definition. It's quite a convenient to define the term in a way that makes it vaguely pejorative, in that case. The fact that you set it up as a contrast to liberal democracy is a good illustration of that. Populism, like elitism, can be right or wrong for a given situation depending on context and policy details.
