Hello.
I addressed this mostly on the Patreon post, you can read my reasons there but essentially - it's not something I can feasibly do.
As far as being unable to purchase, I'm not too sure why that is. You can try reaching out to Patreon to see why you're unable to contribute. I don't use Paypal as a payment processor (too many scammers and they do shady things).
Other than that, I hope you can get it sorted out.
