Nothing wrong in any of those statements. But it doesn't address the problems of competing against the other home made soapers who are doing the same thing. Making the same soap that's better than store bought soap. And selling for less than you are.
Again, educating the public isn't a bad thing. But it's my opinion that you first look at being able to compete within your market. Develop marketing that makes you stand out against your peers. Staying with the car analogy, Mercedes doesn't direct it's marketing to the Kia demographics. They're wise enough to know that, even if they can educate those buyers about the quality issues of their product, their time and money is better spent marketing to their targeted demographics. And standing out among their main competition. Other quality car manufacturers.
We should form a soapmakers' union or cartel, because anyone selling under $5 is selling too cheap and then the race to the bottom (undercutting) begins. At $5, it's benefiting the buyer more than the seller, after all the planning, artistic skills, labor, materials, marketing, etc etc are factored in. If people balk at $7 they can go use zest! That can be our slogan. To those soapmakers selling $5 razor thin margins: you're hurting yourselves long-term. Find emerging markets online like Singapore, China, etc that have growing middle classes with a lot of disposable income. Better off doing that than selling local at too low a price.
