Any ultra cheap (sub €1) MCU can be programmed to wait for long times and activate a load, and several dedicated even more cheap chips can be used as well for the purpose. If any 3 letter agency visited my home lab they would find enough parts to build at least one hundred different timers and remote controls to activate bombs. One thing is a tool whose primary purpose is to harm people (guns, bombs, etc.) and a different thing is something that can be misused as such (kitchen knives, screwdrivers, electronic parts etc.). Criminalizing or even restricting the possession of the latter would be a very dangerous practice that could backfire by creating a world a lot worse than the one they want to protect people from.
