Thought about getting one a few months back. But I estimated that I will only save about 10-12 squares of TP per day. Assuming the bidet breaks within 3 years of use, I will probably only be saving about 10-20 rolls of toilet paper in a span of 3 years. Not worth it.
The truth is strictly what the ones in power perceives it to be.
Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
