This isn't the fault of AirBnB - it' sthe fault of regressive governance. In Canada, the government has done a poor job of detecting when a home purchase isn't a primary residence. Since capital appreciation of primary residence isn't taxed, this has allowed many to significantly enrich themselves, especially during boom times. AirBnB was one method they could take advantage of since it was easier than long term rental.

COVID isn't going to make the AirBnB problem go away. This too will become a memory, and people who were putting properties on AirBnB will return, and those who preferred AirBnB to hotels will go back to AirBnB. The solution to this is better taxation policy to disuade people from treating residential real estate as an investment.

I guess you'd rather have an amateur operate on you than a professional? Or how about an amateur build a bridge?

Professional means something more than what you ascribe to it. I understand that in our modern world, people use words willy nilly without any consideration for its actual meaning. Often professional means some formal education, experience and recognition by peers of this achievement.

This is the case with doctors, lawyers, engineers, accountants. And if go to continental Europe, with actors, dancers, musicians, etc.
