Why do parents "have" to travel with young kids?

Mid 30s with three kids under 7, youngest is 2 years old.

My wife keeps feeling pressure from her mom friends and family to take our kids on a vacation (ie Europe, Asia or all inclusive in Carribean) and I'm finding it hard to see the value. Out of the 10+ parent couples with kids our age, we are the only family that has never been on a plane.

My partner and I had a discussion on it and we generally agree we don't want to do it, but why is this such a prolific thing? I know the gram is driving some of it but many people we know don't post or share. I've tried to boiled it down to the below

Reasons to go - Potentially fun new experience sharing with kids - If you are visiting family / someone close (we wouldn't be) - You really miss XYZ food / experience and kids be damned

Reasons I'm skeptical - it's just parenting in a different location - higher stakes, kids will be bored / want to know the next meal constantly, which requires meticulous planning vs. home - Time zone changes will screw my three kids' sleep schedules and we will wander Rome / Tokyo /wherever sleep deprived - Sub-optimal use of finances, we will give them an experience they won't really remember and my wife and I won't really enjoy (parents tell us travelling at this age it isn't fun but it is interesting and fulfilling, but isn't that all parenting?). Cost isn't an issue, I just can't see burning $10k+ on something everyone says "it's so tiring but you need to do it" - challenging logistically, diapers, car seats, favourite toys, etc. It's already tough going to our own parent's - my kids also love being home, going to school/daycare and visiting their grandparents. When I asked my eldest if he wanted to go travel, he said he wanted to be home with us and play board games with ice cream - (update) two of my kids are under 4 and have trouble sleeping through the night and are in diapers, so it's already a bit tough at home

Please help me understand why I should take my young family travelling! Thank you!

Update: I'm not against all travel! Before kids we travelled internationally 2 to 3x a year, our kids are just very young and we are questioning the point. To be clear, I do intend on taking them travelling once the youngest is 5 or 6, at least they'll be sleeping better, out of diapers and be more independent!
