Actually, the people here have been talking about adoption. I just mentioned it. Hell the dev even said that the reason that they wanted the halving was that there was too many coins and not enough use for them. I think people have considered adoption as the weak link in the chain for this coin for a long time.
I think its fair to say that adoption is the weak link for every crypto currency, bitcoin included.
Its not so simple just to say that we need adoption. At this point we can all waste time arguing the supply and demand of the coin but ultimately it comes back to what you have been alluding to: A solid business plan and publicity.
Most people who would actually consider using Potcoin probably don't even know it exists. Right now we are a niche market inside of a niche market. Potheads who like crypto currency.
We all want adoption for the coin. It starts by first letting people know it exists. Participation in events, handing materials out, etc. You alluded to a number of these things and I think you've hit on the head.
Now back to the original point regarding the foundation address...IMO the legitimacy of this code depends entirely on what they intend to use it for. If they are using those coins to fund something that benefits the coin then great. Consider it an expenditure in their business model, which we have all bought stock in. But the question is what benefit? Not all are equal. Funding a legalization effort is great but lets be honest legalization is going to happen anyway. Potcoin funding will make no difference. There are better ways to use those coins. Use them to pay for ad space, leaflets,coin handouts at dispensaries, etc.
Are there plans for signs at this new office? It was announced and very little was said about it afterward. It seems like an excellent place to try and slap a Potcoin sign or something on the outside of the building. Use the 2% in coins to help pay for it. Handouts and working with dispensaries is nice but ultimately you need Potcoin to be seen by as many eyes as possible. Even if it doesn't stick with most of them. People should know what Potcoin is before they walk into a dispensary. That way they can ask about it inside, instead of being told about it inside for the first time. It puts pressure on dispensaries to consider the coin more seriously if people already know about it.
