Pay for Kagi or any other good, paid search engine, which is already superior to Google today?

Right, you get ads, or you pay. Businesses aren't charities.

So the existence of for-pay search engines would disprove the assertion that advertisements are necessary, as there are alternate ways to find information and fund businesses that fetch you that information, without relying on ads.

These are problems unrelated to the topic at hand. We aren't going to solve every bit of this situation in this comment thread.

Who pays for it? Not my problem. I'll use whatever free service exists, there will always be one.

Without a search engine? The internet would fail and targeted ads would cease to exist.

You'll get advertisements, then.
