Well, it doesn't surprise me those from the first world (US, UK, etc...) have little to say when this question is posed directly, being extremely free societies to begin with.
The big issue with a question like this is that it ultimately comes down to competing human rights, basically your right not to be subjected to something, as opposed to your right to do something. Most of the things people seem to wish they could do are illegal mainly to protect someone else's work (if it was yours, and you invested in creating it, you'd probably want to benefit from it and be able to live off your creation), or to not subject society to the results, while advocates disagree (and are winning for the moment) smoking the mighty Ganja is illegal because of concerns over crime if people were to drive while smoking, and of course issues like the odor clinging to people's clothes. It's become more viable in recent years due to all the crackdowns on cigarettes, so if they use similar policies as far as public areas and such are concerned, a lot of the issues will be dealt with.
That said I'm pretty much one of those bad guys, who would argue that to make things better at this point arguably involves stopping other people from doing things, as opposed to wanting to do things myself for the most part. I for example am a big believed in capitalism, but I believe that like everything it has to exist in moderation, as contradictory as that might sound. Right now as far as I'm concerned a big problem in the US is huge corporations, bankers, and a handful of financial gurus who have pretty much taken control of the entire economy and rule like
kings. I'm all for people making a ton of money and accumulating fortunes where they and their descendants can live in the lap of luxury without having to work. The problem is when you get people, and groups of people, who make more money than they or even the grandkids of their grandkids could ever reasonably spend, and then want more. Beyond a certain point it becomes a game to this mentality it seems, but one where the "fun" of building up their numbers comes at the expense of the rest of society. In short, a few greedy buttheads who take it to a whole new level and ruin it for everyone else, especially when the "game" involves keeping people down as much or more than simply building themselves up. I'm not a believer in socialism OR communism, but I do very much believe in taking strong action against the top
of the financial ladder beyond a certain point. If someone has/is worth a few hundred million or even a billion dollars that's fine, but when you look at corporations and banking groups that effectively make the members of the ruling board worth trillions of dollars, that's just bloody wrong. At that point society needs to pretty much be able to say "okay, hold on here, that's enough".
