With laws like this you generally have to ask what's best for the consumer. I'm not sure reselling is.
The current setup gives furniture salesmen a somewhat predictable revenue model and on the strength of the model they can encourage investors to put ip money to make furniture. Changing the revenue model may change how investors look at the marker. Maybe for better maybe for worse. Who knows, but it would be a disruption if IKEA has to adopt this model worldwide.
The thing that I don't like is if you allow reselling then carpenters get less long-term revenue. This will cause them to focus more on getting a big opening month than making solid furniture that might have years of appeal.
Antilop is still $20 at IKEA. Maybe they only sell 100 chairs a month at this point but that's still money coming in rewarding them for investing in ergonomic chair design. I'd rather see them get rewarded for that than for dishonest advertising campaigns because 50% of their money will come from the first few weeks of sales.
