Steam gives you the locks, but you gave away the keys and are now complaining that the lock doesn't work.

Accounts are not hacked. They are hijacked because you were careless with your account information.

If the account was used to break the rules that falls on you. Makes the ban correct.

How do you think I could have given a code when the last time I played was in April? Your thoughts are ridiculous.

Irrelevant.

Also if someone "hacked" your account, it would be the first ever account hack on Steam.

Look at it like this:

1. Someone has to guess your account name out of millions of accounts
2. Someone has to guess your password, out of even more combinations
3. Someone has to guess your Steam Guard code out of even more combinations valid for mere seconds

And all that matching the same account at the moment logging in.

You'd rather win in the lottery than this scenario happening.

Your account wasn't hacked, you probably simply leaked your data at some point in the past leading to someone HIJACKING your account.
