One can define their own copy constructors and assignment operators for
their own classes.

Since signal are not sync all the time but can be async, the argument need to
be copiable to allow this. So you need to be able to copy the arguments on the
signals. Therefore the QObject is not copiable, they cannot be passed as
arguments directly, you need a pointer. The ownership and lifetime of that
object is up to you, but you need it to live until all handler have finish
processing the signal (this can be longer then the signal emit for queued
connection).
If you can easily copy the structure you probably can serialize/deserialize it
or put it into a QVariant, QVariantList or QVariantMap. That would be copiable.
