Because lead poisoning isn't a huge issue for hobbyists.
Common rules are: Work in a well-ventilated area, don't eat while working, don't use your soldering iron to heat your coffee. But those apply while using lead-free solder as well.
heavy metal leaching in rubbish tips is an environmental issue, one being tackled by much of Europe, starting with regulations on lead-containing electronics.
Don't eat the solder? Warning: Pregnant women, the elderly, and children under 10 should avoid prolonged exposure to lead-based solder. Caution: lead-based solder may suddenly accelerate to dangerous speeds. Lead-based solder contains a liquid core, which, if exposed due to rupture, should not be touched, inhaled, or looked at. Do not use lead-based solder on concrete. Discontinue use of lead-based solder if any of the following occurs:
itching
vertigo
dizziness
tingling in extremities
loss of balance or coordination
slurred speech
temporary blindness
profuse sweating
or heart palpitations.
If lead-based solder begins to smoke, get away immediately. Seek shelter and cover head. Lead-based solder may stick to certain types of skin. When not in use, lead-based solder should be returned to its special container and kept under refrigeration. Failure to do so relieves the makers of lead-based solder, Wacky Products Incorporated, and its parent company, Global Chemical Unlimited, of any and all liability. Ingredients of lead-based solder include an unknown glowing green substance which fell to Earth, presumably from outer space. Lead-based solder has been shipped to our troops in Saudi Arabia and is being dropped by our warplanes on Iraq. Do not taunt lead-based solder. Lead-based solder comes with a lifetime warranty.
