Speaking for myself, the primary draw of larger houses are more spaces dedicated to particular tasks/hobbies/etc. So it might not be square footage that's the goal but the higher number of rooms that usually comes with that.
For example my house is ~1800sqft which is very comfortable and a massive upgrade over the apartments I used to live in that were half as large, but as someone who works from home it'd be nice to have one more room than my house has to use exclusively as an office to maintain mental partitioning between work and downtime. Similarly it might be nice for my garage to be a bit bigger so I could better fit in a "workshop corner".
Is that sort of thing needed? Absolutely not and many get along just fine with far less, but it'd still be a welcome quality of life upgrade.
