Dave,

This fails to take into account the digital nature of our 2.4 systems and the inherent error correction digital systems use. Digital systems use a packetized transmission protocal, so every signal is numbered and when the Rx receives a second signal with the same number of a previously received signal (the slightly delayed reflected signal), that command is ignored. Additionally, phase cancelling effect only works if it's 180 degrees out of phase, which is very, very rarely the case for randomly reflected signals.
Also, yes, omni antennas exhibit spherical spreading losses, but ''signal intensity'' is not that important a value, signal to noise ratio (SNR) is the important value. Who cares if the Rx receives 10,000 watts or 10 MW, as long as the received signal is higher than the ''noise'' the Rx knows what to do.
