In short - by lugging a car seat around the airport you may die, leaving your kid with only one parent!
Removal, transport and re-installation of an otherwise car-installed CRS risks damage to the CRS, thereby increasing the risk of death or serious injury in a future car accident when that plane-used CRS is again used in a car. Also, when a person is busy with the removal, transport, and reinstallation of an otherwise car-installed CRS, the person managing such CRS is not watching the child who is to use such seat, thus increasing the risk of death or serious injury of such child.
If people really care about securing their U2 children way more from greater risk of serious injury/death, then they would be better off putting away their phones/tablets/laptops and paying attention to their kids rather than worrying about whether or not to buy a plane seat for a U2 child.
If a parent is not hiring a full-time guard to pay attention to the U2 child every second of the day and night, then the parent is not doing everything possible to reduce the risk of serious injury/death of the child. All those parents without a full rotation of full-time nannies/guards is not doing as much as possible to reduce the risk of serious injury/death of their child unless and until they go broke paying for top-tier child care around the clock, around the year.
