As I said, I started the fundraising for collecting the funds needed for publishing the book. That means I do not have those funds myself, otherwise I would have probably done as you are saying. I am not begging money from anyone. Instead, this crowdfunding works mostly as a pre-sales system: the people who are interested in this book, would have bought it anyway once published, but buying it in advance they allow me to print the book, and for the book to really exist. This has also the advantage of discovering how many people would be interested, and decide if it really makes sense to publish it this way. In this case, yes, the interest is enough to justify publishing it this way. If the interest was lower, a better option would have been using some print-on-demand service to publish it, otherwise many copies would remain unsold.
I also received an offer from a publisher interested in this project, which I refused. Quite obviously (at least for me, and for this particular project).
Lastly, if you really have a book ready to be published, you should consider doing it, what are you waiting for? You may first start by checking how much interest there could be for it (I personally do not even know what your real name is, and what kind of origami you create...), and then you can simply publish it, as you suggested me! Come on!
Again, please, I am not begging. If you are not interested in this project, please spend your time making something more interesting and useful, for yourself and the world, instead of objecting what others are doing.
