I think he is quite right unfortunately as a businessman. Paph interest is vanishing thoses days, there are masses of plants, species and hybrids, wild and seed grown, available, and more coming. The old days where a plant would easily sell for over 500us are gone...
There are many people in the business, many that would buy from Frank or the Orchid Zone roths with FCC parents, buy another batch from Holland, Taiwan, or god knows where and put their parentage with a discount price on the tag...
Be realistic, if Frank sold for 4 millions his entire paph collection, he would have done this amount in a couple dozen or hundreds years. Even the Japanese Deluxe market is completely gone those days, and to predict when it will be up is totally impossible, 1 year 10 years or never. What is sure is that we are in another down era for orchids, similar to the 30's to 50's where most of the breeding plants disappeared in less than 20 years. Being realistic as well, there are few plants alive today that will still be with us in 10 years. Remember the masses of paph bougainvilleanum and wentworthianum imported by Paul Gripp, the hundreds of flasks of hookerae and wilhelminiae by AnTec, the dozen of thousands of roths seedlings, bellatulum album, sukhakhulii album sold by the Orchid Zone? All gone except a mere few plants here and there.
Frank wants to leave the ship before it sinks, and he is quite right...
