It wouldn't be a major problem - there would be no need to rewrite entire acts, tabling an amendment to existing legislation would be sufficient and happens all the time as laws evolve to keep up with and reflect changes in technology. It almost certainly will happen at some point too as relating theft purely to the removal of physical property is an outdated definition.
Can't come soon enough for me!
The law is not as simple as you think, if it was why has it not been done by now, theft is not just removal of physical property, joy riders do not get charged with theft, they get charaged with taking without owners consent. because they have only borrowed it so it is not theft
