Second reason, I think EF lenses will decline eventually and it is better to sell them when they worth the most.

If you believe in rational free markets, then future obsolescence should already be priced in, and that should not affect your decision.

On the original question, I would not acquire an EF lens to adapt to RF, without a really good reason. For example, you might want the extra sharpness and lower cost of an EF600/4 II vs. the RF version of the III. But you would be giving up the improved AF and IS of RF. There may be specific tradeoffs in the various 70-200 options, but in general get an RF version for the improved AF & IS.

If you already have the EF lens, then you may as well continue to use it, unless there is sufficient benefit to cover the conversion cost.
