"just increase taxes" does not work in the real world (especially here it would be close to doubling taxes) and still does not answer why you would want to hand money to everyone across the board.
It also sounds a little circular: Increase people's taxes so that you can use the income to give money back to them.
Giving $1000 a month to 210 million people costs $210 billion a month, $2.5 trillion a year.
I believe that the annual federal tax revenue is about $3.4 trillion.
