Booking.com's entire business is dependent on them being able to advertise the lowest price. If not, then all hotels would just use booking.com for visibility and get all reservations themselves. In short: Booking.com would pretty much instantly go out of business.

If Booking.com wasn't charging any commissions, there would be a strong reason reason for anyone (hotels or guests) to avoid them.

If the difference was small enough, many guests would still book through booking.com instead of the hotel out of ignorance, not caring enough, or because booking provides a better experience.

It'd cut their profits by limiting the commissions they can charge, but I don't see why they would go out of business.

Customers would catch on very quickly. Maybe the sinking ship could float for a little while, but not for long. There are ring effects to consider.
