The problem is that it's really really hard to gulp down 3 bottles of liquor.

Plus unlike G you are not involved in the preparation, a better comparison would be having a substance called super-duper-liquor that you'd have to dilute yourself with water in order to make sure that it's indeed 3 bottles of liquor needed to send you in ICU.

If you screw up the dilution of the super-duper-liquor you can end up in ICU after just a sip, and you'd not notice because it doesn't have a taste or a smell.

Plus let's face it, humans were never made to deal with liquid quantities in mL , we were made to deal in liters or even deca-liters, because that's the measuring unit of the most important liquid for humans: H2O

Few mL of water aren't good for anything.
