Sure, but OP said 2GB. A node able to process 4GB blocks would be able to sync at 2x realtime. Most people who run nodes will probably bootstrap new ones in the future anyway and most people don't need to run full nodes in the first place (the majority don't do so today and haven't since light wallets became available).

To get back to reality, I don't think any sane person has advocated for anything close to a 2GB blocksize cap at any point in the near future. Bitcoin Core uses a maximum 4MB block weight and Bitcoin Cash uses a 32MB cap currently. This cheap VPS could sync the entire Bitcoin (Core) blockchain from 2009 to present in less than 12 hours. The biggest block size cap (not full blocks, the cap) being tested seriously is 1GB. I'm sure you know all this, though.
