Hi tkatt! I really love and appreciate your reply. Anyway to address your points:
I do see your point. It also makes finally having the bricks that you've been eyeing and waiting for for a long time worthwhile.
Yes, I see all these marketplaces and services online now, but I can only imagine how much harder it must have been as a collector without the internet. That being said though, like you mentioned about songs and TV shows - people wanted more (instant streaming, Netflix) than what was already made comparatively more available (DVD vs having to wait for it to air on TV etc). And services stepped in to provide that to people. While great strides have been made, why not make improvements where they could be helpful?
Yes, I guess having bricks so readily available would kill this aspect of collecting bricks, and I can't argue against it. However, I also see MOCs as pieces of art, and bricks as a medium to create those works. Just as an artist working with paints should not have to restrict themselves to the availability and affordability of certain colours of paint, I feel that MOCers should not be hampered by the availability of certain colours of bricks etc. Though I guess you could argue that scarcity breeds creativity!
I agree that clone brands won't be able to have such low prices as they begin to produce their own designs, conduct R&D and license IP. However, I don't believe that TLG runs a charity too. I think they make about 30% margin, which more than covers their overhead. So while clone brands may increase the price of their sets to cover some additional overhead, competition could put resistance on rising set costs across the board. However, you could argue that there may not be competition if a clone brand targets a diff customer segment altogether (e.g. AFOLs).
