I 100% Agree - there is absolutely room and necessity for both closed and open systems.

When it comes to real estate, I also provide my clients (homebuyers) with a closed system - they can give some input for changes, but ultimately, it comes down to me to integrate all these changes and ensure that the design, appliances, fixtures, etc. work with the house in the end.

The average person loves to have an easy-to-use "plug and play" type of system - and this is what typically stems out of a closed system.

Absolutely, there are a great deal of benefits from open systems as well and that's why I think there is so much room for them in our society. Innovation is definitely faster when we have more minds openly working on a platform (just look to the Steem blockchain for a fantastic example!) Thanks for sharing your thoughts @zekepickleman!
