I'm not sure what you've got, but the original poster has an SE/30, which can take an ethernet card. Other compacts can use SCSI-to-ethernet adapters, although I have no experience with them myself (I am mostly into NuBus machines).
If you are just trying to move files as a one-off and sneakernet is easier for that, you may have a point, but if this is to be a regular thing, a network is the proper way. Whether they were designed to be on a network or not is irrelevant unless you are trying really hard to be period-appropriate, but even then, LocalTalk was a thing at the time that Apple pushed, even if not for much more than sharing one LaserWriter between multiple machines. It may not have been commonplace among machines that ended up in homes, but almost all Macs were absolutely designed to be networked. Declaring networking to be an "addition" (whatever you mean by that) is no good reason to not make use of it.
