It buys you enough time to check the journals and see that a group of IPs have attempted various ports giving you enough time to block the IP altogether.
It also buys you disinterest from the malicious host, since probably there’s a hard limit on how many ports they will test, and they will flag your machine as “too much work” and try another.
Again, I agree with you that obfuscation is not security, but it sure does help.
