Why isnt Bitcoin a PGP network like Bitmessage?

[adpinbr]

If people are willing to pay the miners fee, they should be able to send an encrypted message via the blockchain.

Typical use case: I advertise a pair of Alpaca socks on facebook for 5 mBTC by posting a picture of those socks and adding my Public Key.
The client can now use the Bitcoin network to transmit money, but how does he transmit his shipping info? He could use Facebook (or the medium that the merchant advertises his product on) but that would require that service to support this function and be able to track that data, furthermore those backends are not interchangeable, reducing the purchase experience (I frequently see a product I ike on a website and buy it off amazon for just cause they have my payment and shipping info). I propose that we allow the customer to send the merchant his shipping info via the blockchain in an encrypted manner

And now you introduced more bloat into the blockchain, good job.

more bloat??

im sorry to inform you but blocks are not bloated, they are on average only filled 20% of the 1mb limit

imagine it this way, since the blocks were upgraded from 500mb for 4 years and then and then 1mb for a year means

26gbx4= 104gb
52gbx1=52gb
=156gb potential data that could have been filled over the last 5 years. yet currently my block folder (fully synced) sits at under 20gb

meaning there is no bloat at all

It isn't because it was never coded to be, I'm guessing.

You could still embed a PGP message in a transaction and if the other party has the key, they could read it, right?
