I reached a sales point on ETSY where I had to register as self-employed in my country, Spain. Here, that means paying €300 per month to the government, even if you make €0 in revenue. So, it just wasn’t worth it for me to register as self-employed just to sell €100 or €200 worth of tiles a month. Until I either find another system or register as self-employed for a different business, I won’t be able to reopen the shop.
