The largest ground based mirrors are pushing 30m now while the largest space mirror we've built (but not launched) is the JWST at 6.5 which requires a complicated folding mechanism to achieve because it has to fit in a faring. So to make one 30m telescope in space we'd need around 20 JWST sized telescopes plus the cost of launching and assembling them in space which currently means using people. That's far from a small tax.
