I like to promote the postcards option because the postage is cheaper than
letters if not done regularly.

Yes, but like I said, can be written to only once.

they can probably invest in an additional consumer grade reader/writer (for
offline usage) too.

Which my idea avoids, i.e. using super über mega cool local postal services,
to support our *hard working* local postmen, instead of globally supporting
people with root privileges etc! :-D

Remember even Russian authorities, according to reports from 2013, are using
German typewriters now, which means, at least to me, that the smart Russians
are using their postal service too, or couriers, instead of email. ;-)
