A Shariah-compliant world?

A few pointers from yesterdays's discussion that requires further thinking.

Practicality and function

1. Halal certification is necessary as a means to validate halal-ness of food intake for muslims. It is the determinant of whether certain food choices are open to muslim adherents or not. The limitation is that when you see food stalls / street food vendors not having halal certification, due to business non-compliance or increased costs, but you'd assume it would be halal if it was a muslim vendor. If you visit a muslim household, no questions would be asked. 
2. We then examine the perimeter of that assumption. What is the expected behaviour when visiting a non-muslim household? Alcohol and pork are clearly unacceptable. Would we need to examine the source of meat? Or refrain by just eating vegetable and pastry? What if pastry is made using wine? Or vegetable dishes are made using alcohol? What about utensils? Should they obtain halal certification before inviting guests? These are valid questions.
3. What then is the outcome of examining the perimeter? Would Islam, a very social philosophy outlining leadership of community based on principles of humanity, enlightened by divine guidance, accept the unintended outcome of a stratified community where the ones who want to safeguard their iman are 'locked-out' from mingling, as food (and halal drinks) are perhaps a common denominator for humankind? Is this a call for muslims to dominate the food supply chain?
4. Would JAKIM and other halal certifying bodies be able to absorb the latest capabilities for traceability, and therefore uncovering that non-halal sources could be used for many processed food and medicine? Would halal stand for healthy, or just halal? What is the standing on the many halal but uncertified food products, or halal food products that may use non-halal sources (but converted within the process).
5. It would seem that in its current state, the individual is required to find the answers from his own trusted Shariah source, and apply the above within his daily behaviours.

Then, for a Shariah-compliant product financing. I'll admit the crude and clumsy jump in the analogy being used.

1. Shariah-compliant, I'll just use Green, is a way to identify public listed entities by filtering out the ones with dodgy business fundamentals, and the ones using dodgy capital sources, e.g. non-Shariah compliant loans and such. By that, muslim investors can choose green assets to fit his green portfolio. The intent is rather different in this case to food, which is a basic necessity, whilst for financing this can be hajjiyat in nature. I'll just dodge the Islamic banking products for now as it's a means to open muslim adherents to participate in banking operations for now.
2. Private financing then can be a bit fluffy when it involves preferences. Malaysian standards that allow for preferences when combined with waivers is a nice solution to bringing the same standards into play.
3. Now, slight issue is - where or when does private muamalat become non-halal? My sense is that when the principles of equality, justice is not served. Would backing out / locking out muslims from participating in hajjiyat financial practices constitute justice, especially so when wealth creation activities are centred on technological progress?
4. This is my biggest beef with yesterday's discussion. I understand the principles / guidelines for shariah-compliant exists and will be the perimeter within which the edict can be issued, but stepping back I can't help but feel that more needs to be done to develop new principles / guidelines that allow muslims to develop - fast.
5. I would perhaps just put it out there that private transactions - that were willingly entered into by two participants - if judged as unethical from a third party from one lens is insufficient to call it within or without compliance. Risk taking, and the ability for a VC to take on bad decisions as part of a learning process, whilst enabling the creation of a bigger pie for both the VC and the entrepreneur to succeed in their endeavours to create a better world for humankind seems to me like the area that the Shariah should be most concerned with.

Zaharudin, MAZA and Zabidi springs to mind. Could just be my inability to articulate the need but I can't help stepping away from the meeting thinking that it seems like a reform is needed.
