No, it isn't "just as safe", by any stretch of the imagination. "Safety", in the context of investing, refers to the distribution of possible outcomes around the expected return of an investment. In most instances, diversification will reduce the standard deviation of the expected return of a portfolio, without sacrificing the expected return. In other words, a diversified portfolio is safer, all else equal. This has been known for at least 70 years. You're not providing any counterpoints to established investment theory. You're simply making false claims that contradict both the theory and the empirical evidence.
