Small contradiction there on the role of realtors and investors. Add drag to trade really hits the investors. Look at the Netherlands, recently the buying tax has increased from 6 to 10%+ when buy to let or flip. Consumers buying a home pay only 2% tax. After this (+current interest rates, +some other factors), the professional home investment market in NL completely dried up.

For the rest totally agree, disrupt the middle man in real estate is OK++.
