I liked this - at first I disagreed with it - (my footprints can be saved,by my childrens memories) - but then I realised that that that won't last forever! - very thought provoking.
Nor lose possession of that fair thou owest;
Nor shall Death brag thou wander'st in his shade,
When in eternal lines to time thou growest:
So long as men can breathe or eyes can see,
So long lives this, and this gives life to thee.
I think, I am more inclined - call it my outlook - to agree with you, not Shakespeare - "Footprints can't be saved", Men won't breath for ever...
