Create beautiful, fast and very lean web serivce - "easy" part. It should be very lean - every page at most few hundred kB.
Serve the website with useless bytes at front. Example: page weights 100kB - add 500kB of garbage to it at front. You can place them in html or js comment. You can add useless EXIF data to jpegs. You could place small number in every HTTP header. Or you could add artificial latency to every request.
Then you sell those useless bytes or milliseconds. Your bytes could really be unicode glyphs. Example: a dollar for every byte per month. When a user leases a specific byte you can send it to him by an e-mail for increased silliness factor. He leased it, so it will not be sent to anyone else as long as he pays.
That way you can specify a ceiling of profits. 500kB at one dollar per kB can bring you at most $500k per month. It seems fair, a bit like Patreon targets.
I thought about doing a service this way. And even a platform - providing web server configs and plug-ins that would do all this selling of bytes process, also payment processor for bytes that would also run on the idea.
