When people say they they love a challenge and move ahead when experienced others advise caution, although it sounds cool and brave, frankly it’s silly will result in failure or a huge waist of money and time at the least.
Lugged construction takes four times as long as tig welding, and involves a much wider skill set. Aluminum might be hard, but it is commonly accomplished with autofeeding pulsed welders. Or even MIG. Making a decent looking Ti weld may or not be hard, but actually making one that won't fail a year later is clearly difficult.
But if your point is that the OP is overestimating their ability to acquire the skills and execute a thin-walled frameset in little time - I agree.
