Blur v Opensea driving take rates to 0 makes me bullish on crypto. 

To me, one of the biggest value props of crypto is getting us closer to the efficient market and reducing rent extraction. 

Tokens potentially align incentives here, Opensea yet to crack (maybe doesn’t apply in this case)

But how do companies make a profit in that case?

Building /stokefire a mobile strategy game onchain. Run and own poolfish.xyz a calculator for LP providers. Built Potion solo and sold for $300k.

A few things:
-Protocols don’t need to profit

-OS has made a ton of money to this point, just because they don’t have a long term sustained profit engine, doesn’t mean they can’t profit

-By doing things that are differentiated and value add. For example, their APIs are very useful and benefit from economies o

Seaport is a protocol that Opensea builds and productizes in the same way Farcaster is a protocol that warpcaster / mmc builds. 

Opensea will need to find other ways to profit. I think they can!

Profits are value transfer from users to companies. Less profit is good for consumers.

"OS has made a ton of money to this point, just because they don’t have a long term sustained profit engine, doesn’t mean they can’t profit"

How do share holders profit? How many businesses destroy their main engine of profit and survive? Where is OS a Protocol?

Opensea isn’t but Seaport is.

Of course they need to make money, but they should make money in the places they provide differentiated value.  I believe both will be able to…and if they can’t, they’ll die and then the other can start charging fees again.

I'd say both Blur and Opensea are not protocols. 
They need to make some money if they are going to continue to deliver a good service.

API like you mentioned could be a good way I guess.

I'm very interested in the idea of how protocols can capture the value they are deserved.
