Falcon heavy is only $1,500/kg to LEO. This rate is considerably undercut here on Earth by me, a weasley little nerd, who will move a kilogram in exchange for a pat on the head (if your praise is desirable) or up to tens of dollars (if it isn't).
Does your transportation system also have a risk of exploding catastrophically mid-flight? 'cause otherwise no deal. /s
In exchange for what benefit? There is literally no benefit to having a datacenter in space.
The benefit is capturing a larger percentage of the output of the sun than what hits the earth.
Can that really work? The datacentre will surely be measurably smaller than the earth.
