If you see one person buy something then not use it, that's a fact, but if you see a lot of people do the same then it is a pattern. If there is a common pattern of people buying "betterment" products then not using them, you should evaluate why you won't be yet another statistic.
I use my standing desk for reference, but the larger point is that a lot of people buy them and then don't use them for whatever reason. Likely don't think through what they're trying to solve and how often throughout the day they think: "wish I was standing right now."
This issue is a reason why you should buy the cheap version of whatever it is first, then upgrade when you out-use the cheap one, rather than going all in on those $500 shoes or that $1500 exercise bike. Applied to standing desks: Try a "Standing Desk Converter" or a cheap IKEA standing desk for $300 instead of a high end motorized one for $1K+.
