Heh! Speaking of brick walls here's a shot with the "old" Canon macro:
But as to software processing replacing good lens/gear, well, for some things "work" is involved rather than "visualizing" and capturing your scene/subject in a way that communicates your vision. For example, here's a couple Macro shots, I shot the first at f/16 and the second at f/8 because that enabled me to get the flowers in focus, but I knew that at the close "macro" distance I'd get a reasonable background blur...
Now, sure, you can take alternative approaches -- multiple shots and blending, using software blur tools, working on creating the tilt and shift "effect", sure, if you have put in the time and effort to learn those things, and take the time to get them to work without the results looking "fake", well sure -- think of the work involved in creating the visual effects in cinematography to get the amazing "look" of, say "Jurassic Park" or on a smaller scale "The Hobbit/Lord of the Rings" films...
But then, take this shot I got at a local rodeo, not just not just visualizing the scene and then carefully watching for "moments", but I used my trusty gear (including my expensive 1DMkIII camera and my high-quality 70-200 "L" lens so that when the "moments" came I could capture several "takes" that could render decent quality images, in exposure, focus, "motion grabbing":
Now, if you can grab a kit lens and capture a similar scene, and with software make up for any "gear shortcomings", why go right ahead, I'd love to see the Before/After results!
