I do wonder if a workaround here is buying a physical postcard from a patreon creator that comes with a free monthly subscription. A 50c mailed card would be cheaper for any subscription above $2.
I'm not sure you'd need to ship it. You're buying a 1/100,000 share of a physical postcard that exists at the Patreon offices. You can visit the office and see the postcard displayed out front under glass. It just so happens that buying such a postcard includes a free month's subscription to a Patreon creator.
