that is easily true. You buy a house for $500k. A year later, you decide to move. The house's value remains at $500k. Realtor commissions of 6% cost you $30k. You lost $30k on the total transaction, the realtor made $30k (not including the original buy).
Only on HN would I see someone argue that depreciating or stagnant assets are the same thing as a 30% transaction fee. This community is smart enough to be able to tell the difference between a tax on revenue and a tax on profit.
Apple is imposing a tax on revenue that is higher than the revenue that Patreon pulls in from each transaction fee.
There is no equivalent situation in a realtor market. In no world would a realtor sell your house for $500k and then tell you that they deserve a higher cut of the revenue than you do.
