Sell something without the extra costs and will people pay more? In the housing sector in the UK that's certainly not the case -- people didn't value freehold over leasehold until lots of media coverage, despite the information being right there for all to see.
In a situation where there's a monopoly/cartel, the consumer that actually looks at the total costs and benefits can lose out because there aren't enough knowlegable customers to make an old fashioned business viable, but in industries with low barriers to entry and low network effects it's not a problem.
