Good arguments that Model 3 is a great car. But not very relevant to the question of whether it is a mainstream one. Apparently many people are not in a position to value their lives as highly as you do, or at any rate choose not to do so.
Many ICE manufacturers upcharge for "special paint", wheels, etc. Look closely at the window sticker the next time you shop for an ICE. Besides, ICE isn't EV. The long term benefits for EV are unquestionable. See you at the gas pump! NOT!!
