I'll give you that point. Nobody knows what the right thing to do is nowadays. I have friends I trust who say, "Buy rental property, buy gold, put it all in stocks and hold on and pray, etc." It's a scary world. The best thing is to have skills that are rare and in-demand and a good job with a high-salary. Of course, easier said than done!
If a young person asked me for advice--not that young persons listen to anyone these days--I'd say get a degree in petroleum engineering or something like that, don't hold debt, pay the credit card off in full each month, and live way below their means.
I think this discussion is on topic because it gets to the heart of the OP`s question. Is a Sebenza worth it? Well, I think for most people the answer is probably "No." But if your financial house is in order and you are experienced enough with knives to appreciate it (and not just want one because all the cool kids have one), then the answer is probably "Yes."
