Crazy finance rules surrounding current protection product (4,9)

Ross

I believe the answer is:

life insurance

I'm a little stuck... Click here to teach me more about this clue!

'protection product' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'crazy finance rules surrounding current' is the wordplay.
'crazy' indicates anagramming the letters.
'surrounding' indicates putting letters inside.
'current' becomes 'I' (symbol for electric current).
'finance'+'rules'='financerules'
'financerules' with letters rearranged gives 'lifensurance'.
'lifensurance' going around 'i' is 'LIFE-INSURANCE'.

Can you help me to learn more?

(Another definition for life insurance that I've seen is " Cover against one's demise?".)
