In that discussion I forgot the key point. The most important factor in 
regards to cost is not the development cost.
The key cost factor is what they would charge per flight for a reusable 
launcher. Robert Zubrin made this point insightfully in one of his books. He 
recounts that he made the argument for reusable launchers in his former job 
with one of the big launch companies.

He argued that they could cut the cost of launch by an order of magnitude. 
The company execs responded: why would we do that? Their view was their 
revenue would then be slashed by a factor of ten. They were assuming the 
market would still be the same but they would be getting one-tenth the 
revenue.

So the OldSpace companies were acting quite rationally in a business sense 
in discounting reusability. They were saying the market was not enough to 
make it advantageous to them.

But if there were a large market then they would make more money making more 
launchers at the lower price. That is, the price would be reduced by a 
factor of ten but the number of launches would be increased by more than a 
factor of ten.

Also, the importance of the large market and lowered prices for satellite 
launches extends beyond that of just the satellite market. By making 
launches at such reduced prices, that increases the possible market for 
passenger flights to space. So the impending megaconstellation launches may 
also bring to fruition the long desired routine passenger flights to space.

Single-stage-to-orbit was already shown possible 50 years ago
with the Titan II first stage.
In fact, contrary to popular belief SSTO's are actually easy.
Just use the most efficient engines and stages at the same time,
and the result will automatically be SSTO.
