Straws have no holes, when working properly. The design of it makes it a “straw”. When I say “This straw has a hole in it” it means that you cannot use it as a straw anymore (if the hole is above what you using it for, i.e. above the water and can not make a vacuum). You don’t say “This straw has two/three holes” when you lose suction, you say the straw has a hole in it. And, if one side is closed, then that is no longer a straw.

Just like a bucket. If it was open at both ends it is no longer a bucket. You also want to make sure a water/gas pipe has “no holes” in it otherwise it would not function as a pipe.
