You guys are not being nice.
I don't think anyone has anything against casascius, this is a theoretical/practical discussion of the merits of his proposal.

This is really no different than bitcoin4cash or cash2bitcoin where people send envelopes stuffed with cash to complete strangers!
Not quite, they receive/send you Bitcoin, which is a final transaction and should immediately be obvious whether it worked or not. The proposed scheme here could retain or lose in transit the private key, which can be used to control future balance in the associated account. It's like introducing the possibility of chargebacks, except on all of the balance as long as the account is in use
