No. This is the same as someone saying that
"Thor is basically a large scandinavian brandishing a mystical hammer. That's all he does."
Galactus is a semi-abstract entity. Semi-abstract because he is the joint union of two beings, the mortal Galan of Taa and the Eternity of Galan's reality, or in other words, current (i.e. 616 Eternity) Eternity's predecessor. This is, on a very basic level, similar to Eddie Brock (Galan of Taa) and the alien symbiote (the Sentience of the Universe, aka the previous Eternity) forming Venom (Galactus).
As Utrigita already mentioned, Galactus represents Equity, Death represents Vengeance, and Eternity represents Necessity. These are the three fundamental forces that prime 616 Marvel requires to exist. Meaning if any of these three fall/die with none to replace their duties, the marvel universe ultimately collapses and ends.
He is not a true abstract in the sense of using M-bodies to manifest (he does have a physical presence), but he is every bit abstract in authority, status, and-depending on how much his hunger has been satiated-power.
Remove Galactus from the universe and the antithesis of multi-eternity is released, Abraxas, embodiment of Destruction.
Remove Galactus from the universe and the balance and natural equilibrium between the two concepts of Eternity and Death becomes unhinged, leading to the collapse of the universe . This is all on panel and has been stated many, many times in regards to Galactus.
Your statement couldn't be further from the truth.
