One consequence of legalizing jaywalking, may be increased prevention by fences and barriers. Low railings may be jumped by an agile adult, but they stop children, elderly, wheelchairs, pushchairs, suitcases or people with heavy shopping. Divided highways may get (more) high fences in the central reservation to deter jaywalking - but of course the frustrated locals will eventually cut convenient holes.
