Because they have created an imaginary world from the description of an non-existant gas with no properties, so actually, really, with nothing for gravity to work on, so, their ideal gas molecules have no weight relative to each other so they can not separate out as real gases do, have no attraction so can not form a medium or combine, are nothing so there is nothing to undergo chemical changes, etc. etc..

Ideal gas which has no mass therefore no weight under gravity because there is nothing on which gravity can pull; which has no volume therefore does not expand or condense changing its weight under reduced and increased pressure or heat and cold and so does not become lighter or heavier than air under gravity; with no attraction therefore merely capable of bouncing off another and not capable of undergoing chemical changes, such as water and carbon dioxide in the atmosphere forming carbonic acid.
