Why is it necessary then?

Defined blocks can take arguments, where broadcasts are usually just to continue a script across sprites...

It's meant so that your scripts are smaller. For example, you could change this:

repeat (10)
change [color v] effect by (25)
glide (1) secs to x: (2) y: (34)
say [Hello!] for (2) secs
play sound [Pop v] until done
end

into

block

which is a lot easier than doing the first script over and over.

It can also be shared across sprites, reducing the need to duplicate scripts.

That's the same thing I was thinking! It's pretty much the same as broadcast and wait.
Because here are what is the same:
Define script, (when i receive), and it would pretty much act the same.
I'm not sure but there must be some reason.

You can make blocks that do not require screen refreshes. Good for terrain generations.

procedures can be atomic

it is also easier to manage a procedure with arguments instead of a broadcast with many variables.
