>Blocked by whom? If the relay (which pulls records from your PDS) “blocks” your PDS, you can simply switch to one that doesn’t.
Blocked by pretty much everyone, in the case of email. If most people use gmail or hotmail, and these mail providers block mail from new domains regardless of DMARC/DKIM/etc. then you are effectively blocked from sending email to most people. It's inevitable that this happens because there is no sybil resistance built in to the network layer, so providers have to be blocky to prevent spam.

So kind of like how in the web, every website can be run separately?
You can switch, but everyone else won't coordinate to switch at the same time. So you have been deplatformed. It is the same with the web, where if you get banned from a forum (perhaps one that changes its rules to suit sponsors), you can switch to using a forum that no one uses due to network effects.
