A lot of that could be mitigated by finding products that are bottled locally in reusable bottles. I don't know about other countries, but that's become all but illegal in many US jurisdictions.

re: frosting, it really depends on how how you like your beer. If it's an American pale lager like Miller or Budweiser, where the defining feature of the style is that it's meant to have as little flavor as possible, yeah, a frosted glass will help with that. As will a bottle, since bottles are perfect for minimizing your nose's exposure to what you're drinking. If it's an ale that's meant to have a lot of complex flavor and aroma, and you like those things, cellar temperature will bring them out more.
