Going on a little rant that has (mostly) nothing to do with Kagi: the state of online payments is pretty grim for anyone that wants a little bit of privacy. Even with privacy focused services such as Kagi, Tuta, Proton, using crypto is harder than using the default mainstream payment services. I don't want stripe, or paypal, or anyone for that matter to know where my money is going, why is this so hard? Even crypto which was partly supposed to fix this is in a bad state where the only source to easily find it is through centralized exchanges that demand ID checks and what not.
The best way I found so far is to use a regular exchange and use it to buy Monero and withdraw it to my wallet, since it's the only true anonymous coin.
I know there are laws against money laundering and terrorism and I don't know what else, but those people will continue to use hard cash and gold and other sources, meanwhile the average joe that just wants to pay 10 bucks to search stuff on the web has to fork out his entire personal life details to a bunch of middle men that take a slice of that money and still sell your information to the highest bidder
