But if Bitcoin will have its note version, that would be a digress from its being a digital currency.
Not only that. As much as I want bitcoin to have a physical note version, for bitcoin to have a note version, you'd have to trust a centralized entity(like a bank LOL) to actually print the papers, with at the same time, making sure that it doesn't become IOUs like how fiat money has become. So yea, it would completely defeat the purpose of being decentralized.
Would love to own one of those, are they one sale somewhere ?
Print it yourself instead. Here's a high-res version from the Reddit post:
