Interesting stuff
@pie-man as you say perhaps some controversial points raised in your post.
It was a few years ago but my club did play against Middlesex ladies, there were some England players there although I cannot remember their names.
I played and technically most of them were very good, pace wise our club bowlers did cause them some discomfort, none of theirs did to us, but.....technically the batters were pretty good and had been coached it was obvious.
Physical fitness probably has improved in recent times for the women, they move towards a professional game, I don't think they are classed as ameteurs any longer.
The physical strength side of it I don't know how much that can improve, I suspect there will be others on here who share different views
There is a comparison with tennis I think, how many people want to watch the sport will determine prize money, tv coverage etc.
But the women game is developing and there is still a significant gap to the men.
How much that gap can and will close in the future I don't think anyone knows,that's presuming stumps flying and big sixes,bowlers up to 70-80 mph is want people want to see-with the men's game as an example
