Not going to argue about whether or not it’s constitutional (because I don’t know), but I just wanted to point out that this case is slightly more complicated than just “you’re not allowed to purchase”. It’s “you’re not allowed to purchase… BUT other people are”. Which means it’s potentially a question of discrimination, which is maybe not as cut-and-dry as a “normal” law banning a substance across the board.

Cool explanation, but that’s not what echolocation means

It would be if the dog had a good reason to believe that it would get to the bone if it kept digging

Measuring by mass is definitely more accurate, yeah (for dry and wet ingredients). But have you ever noticed that the recipe always uses round numbers? You never see 4/9 cup, or 2.3735 teaspoons. What’s the point of being able to measure out an exact number of grams when the recipe is already extremely approximated at a not-necessarily-exactly-optimal amount?

I mean yes, ok, I admit that you will get more consistent results. But not necessarily consistently good results.

“if and only if” is an unusual and sometimes confusing way to say it, but the words do directly imply the technical definition.

“it’s an apple if and only if it’s a fruit” literally means “it’s an apple if it’s a fruit” and “it’s an apple only if it’s a fruit”. You already seem to understand the 2nd part, so no need to explain that.

The first part is a bit confusing because the words are in the reverse order compared to how people normally talk. “it’s an apple if it’s a fruit” means the same thing as “if it’s a fruit, then it’s an apple”. Clearly “if it’s a fruit, then it’s an apple” is not a true statement, because there are plenty of other fruits apart from apples.
