I personally find that [high quality] outdoor is akin to a beer after work. It helps you wind down after a stressful day. An hour or two later and there are no lingering effects, it's great for a touch of relaxation. I find that I can carry on being productive even while high.
Conversely, indoor tends to be more like sharing a bottle of wine with someone - you're going to get far a stronger kick out of it and it's going to last longer. It also tastes much nicer.
I'm not disputing what you're saying, growing outdoor is cheap (virtually free) and therefore attractive. Typically there is little pride involved and the quality suffers. However, well-grown outdoor fills a niche just like well-grown indoor does. It merely has a bad reputation.
