which defeats the whole purpose of Bitcoin that you should trust no one to validate the entirety of your coins history

That is not true.

A pruned node downloads and validates the whole history since the genesis block. (Sync is identical to a normal node) It simply doesn't save it all to disk.

pruning is not the same as a checkpoint which is what Adam proposed. either way it still has to sync entirely as you've mentioned so:

Assuming yearly 20% increase blockchain size & 10% reduction in bandwidth costs, after 15-20 years no new nodes can enter system except maybe huge datacenter operations. https://www.youtube.com/watch?v=TgjrS-BPWDQ&feature=youtu.be&t=7331
