Not only an untrue statement, but also a sadly incurious way to approach someone else's design choice. Yes, it was an enormous amount of work and invention to achieve a desired effect, but the effect is striking in an environment that is otherwise plastered with everyday visual clutter.

Minimalism is difficult and expensive to achieve. Some people consider that effort worthwhile.

I dunno. Premium products are a difficult thing. I can't weigh in because I don't care about cards at all, I'd much rather receive a wedding invitation via e-mail yet people spend hundreds on custom cards on thick card, custom printing etc etc. In fact, some couples are insistent on getting their wedding invitation envelopes "hand cancelled" so they look crisp and clean when they arrive at their destination:

If you're one of those people I could absolutely imagine you'd care about a visible barcode on an envelope. They kind of have to be premium products because if they’re blah then people will just use evites, which are better in a bunch of functional ways. The product relies on its differentiators.

Someone who cares about the barcode tends to care about other details. In some ways it's like the band riders that have silly things like no brown m&m's.

I think many failed/aborted projects only seem stupid in retrospect because we assume it proof they could never have succeeded .. but many ridiculous things can and do succeed and find their place. It fizzled after his death without anyone championing it with persistent care and constructive iterations. It may well have ultimately failed, regardless, but it certainly lost its motive power.

When you’re sending someone a personal card barcodes makes it look very impersonal, maybe even makes it look like junk mail.

Clearly one person did.
