Sure he had a solution. The solution basically is for everyone to only use the P2PKH addresses. (The ones that start out with a 1.) Basically it is a rejection by each individual user of the segwit/LN solution to scaling that the Bitcoin Core team has implemented. From what I can extrapolate from his arguments is that BTC is really only meant to be used  as a store of value and to transact with large sums of value. So scaling is not necessary. The wealthy do not mind paying the high transaction fees to move large sums of value around. Also, according to his arguments, the wealthy elite don't want some platform that is going to constantly be changing. They would prefer something that is immutable and demonstrated to be secure. When changes are constantly introduced, it is possible to have some insecure vulnerability be introduced and have some black hat exploit it. If someone wants to use cryptocurrency as a means to handle everyday expenses, then he recommends people just use one of the multitudes of altcoins available.
(Please note that me trying to summarize the gist of what he was getting at should not be construed as a total endorsement by me of what he proposes. Also, I may still be misunderstanding some of his points. So my interpretation may be totally out on left field.  )
