For someone who might not be a native English speaker, or someone otherwise unfamiliar to the English language, "validate" may not be a very familiar English word. Especially if they're only used to using English for talking to people for normal conversation, I don't think it would be very natural to use any variation of the word "valid" constantly in conversation, unless you're trying to be captain of the debate team, president of the science club, vice president of the fashion club, or are only talking to customer service representatives.

If we want to go down that route I’d say they’re more versed than they are letting on. When you consider structure, punctuation, etc. regardless, a dictionary or a Google search would solve it. Valid can come up more than you realize. “Valid point” as an example.”validated parking” as another. Or seeking validation via likes on a forum post.
