But this is not comparing apples to apples. Smoking weed in moderation is probably fine too. The trouble is criminalising it means you can essentially only buy the weed equivalent of cask strength moonshine, and nobody knows how to mix a nice cocktail.
Decriminalising would make it (more) possible to grow and sell lower THC weed, and weed with different cannabinoid profiles. We still know very little about the differential effects of THC/CBD etc in weed as-smoked.
In short, I think your advice is probably premature. Let's try legalising and developing a stoner culture which isn't the equivalent of hardcore alcoholism, then try comparing. Plus, drunk people (> 2 pints) are also seriously boring if you are sober.
