While it may be true that you don't have a problem with spam ("mostly")
just think of all the bandwidth the spammers clog up while sending you
email (that you don't "see") and your email client bouncing it back. It
slows down the whole internet for everybody.

And you are so naive that you don't know that spammers are sending spam
to your phony email address, then being bounced back?
