It is difficult to allocate resources/funds because as citizens we all want something different? True or false

Left to its own devices, a free-market economy will not result in the level of environmental quality that people want.  Firms pollute, and people make expenditures without concern for environmental consequences.  We need some level of government intervention to ensure those decisions take account of other people’s concerns.  However, regulation cost tax dollars and is an infringement of liberty. How can we determine how much environmental quality we want and what is the best way of getting it?

Should the government provide more and more public goods, so that we move increasingly towards a 'welfare state'? Why or why not?
