Because if they weren't, I'd gift my work to my employer and they'd gift me money to live on. And there would be a similar exchange of gifts with customers and suppliers, rather than purchases and subscriptions.

The paperwork only starts when you gift one person more than $16k (2022 value) in one year, which is quite a large gift and the lifetime estate tax exemption is also very high (currently $12M), so even if you do need to file paperwork because a gift is taxable, the tax rate is likely to be 0% for almost everyone. And as much as people complain about death being taxable, most people don't have that many tears for the tax impact on people who had a $15M estate.
