The question is not the goal, but what they are measuring by immersing someone in water.
Weight can certainly be measured by floating an object and measuring the displacement, but this is not the reason for using water. A halfway decent digital scale will give weight to a fraction of an ounce without requiring a person to get wet.
The reason for using immersion is to measure volume.
I do enjoy these discussions, however. I haven't had so much fum since someone argued that 1^720 was a really big number and that a circle is not an ellipse.
OF COURSE the question is the goal, when it's obvious no one cares about volume other than how they ultimately measure body fat PERCENTAGE with it!

Then there'd be no reason to dunk someone in the tank in the first place, because NO ONE is interested in a person's volume!

Nah, you just enjoy being obtuse while incapable of ever admitting you're wrong.
Well, it is infinitely larger than zero... ;^)>
